Aging Eyes and Driving Safety in Ft Lauderdale

Even if you don’t have any eye or vision problems, the natural process of aging affects your ability to see and react to visual stimuli. It’s important to know the impact the aging can have on your eyes and vision so you can take the necessary precautions to stay safe and protect your eyes.

Driving is one activity that can pose a high risk as safe driving requires not only good vision, but also intact cognition and motor response. As we age, reflexes, reaction time and vision begin to deteriorate, which can impair one’s ability to drive safely, particularly under conditions such as bad weather, twilight glare, or nighttime darkness. Here are some ways that your ability to drive can be impaired as you age and some safety tips to help you to stay safe on the roads.

The Aging Eye

As we age, the eye and vision naturally begin to experience a decline. The pupils in the eye, which allow light to enter, begin to shrink and dilate less, allowing less light to enter the retina. This causes reduced night vision. Additionally, some of our peripheral vision diminishes along with our ability to see moving objects.

Due to deterioration of the cornea and clouding of the lens of the eye, glare becomes more disruptive and contrast sensitivity is reduced, making it harder to perceive images clearly. General imperfections in vision called higher-order aberrations cause a general decline in vision that can’t be corrected with glasses or contact lenses. Additionally, our reaction times slow, adding motor complications to the visual ones. Dry eyes also becomes a bigger problem with age as the lacrimal glands don’t produce as many tears to keep the eyes moist. Many of these symptoms may be present without the individual even noticing a decline and can all contribute to increased risk – for the driver, and others on the road.

If you add in any other vision problems such as cataracts, glaucoma or macular degeneration which are age-related diseases that gradually reduce vision, you can have a serious danger on your hands.

Avoid Distractions

The biggest driving distraction in our day and age is cell phone usage. While many states and provinces have created laws which forbid driving and texting or holding a phone, it is not universal, and this still causes countless accidents and deaths that could be easily avoided. Even hands-free options distract you from the road and put you at risk. If you must use your phone to speak, dial or text, pull over first.

Plan Ahead

If you can avoid driving at night or on hazardous roads with sharp turns, inadequate lighting or that are unfamiliar to you, you will be better off. Plan to make first time trips during the day when you can clearly see street signs and landmarks or take a practice trip with a loved one.

Purchase Night Vision Glasses in Ft Lauderdale

There are glasses available that can help to reduce the glare at night and enable better night time vision. Speak to your optometrist about whether this is a good option for you.

Turn Vents Down

Car vents can also cause discomfort, eye irritation and create greater vision hazard, as the air blowing at the eyes can impair vision or cause watering, especially when the eye are already dry.

Maintain Good Eye Health

Make sure that you get your eyes checked on a regular basis and that any eye conditions you have are being treated and monitored. Good nutrition, exercise and overall healthy habits will help to protect and heal your eyes as well. Further, listen to your instincts, if you feel unsafe driving or if your doctor (or family members) tell you it’s time to hand in the keys, think about utilizing other means of transportation to get around.

Many times people are able to pass their vision test at the driver’s license bureau which gives them a false sense of security, but in reality they are not seeing well, especially at night or in bad weather. In many areas there are courses available for senior citizens to test out driving skills with instructors who do an evaluation and give feedback on their real abilities. It’s critical for seniors to speak to their eye doctors about their true vision level and any restrictions that they recommend.

The key to eye health and safety is awareness. You can’t stop your eyes from aging but you can take the necessary precautions to ensure that you are protecting your eyes, yourself and those around you by knowing how your eyes and vision are affected.

Are Your Eyes Sensitive to Light?

Light sensitivity, also known as photophobia, is a condition in which bright light – either natural sunlight or artificial light – can cause significant discomfort, pain and intolerance. People that experience light sensitivity will find themselves needing to close their eyes or squint when exposed to light and often experience headaches and nausea as well. In mild cases, the discomfort accompanies exposure to bright lights or harsh sunlight, but in severe cases even a small amount of light can cause pain and discomfort.

Photophobia is more common in individuals with light eyes. This is because the greater amounts of pigment in darker eyes help to protect the eye from the harsh rays of light. The darker pigment of the iris and choroid absorbs the light, rather than reflecting the light and causing internal reflection or glare experienced by those with lighter eyes. People with albinism, which is a total lack of eye pigment, also experience significant light sensitivity for this reason.

Acute photophobia is usually a symptom that accompanies a condition such as an eye infection or irritation (such as conjunctivitis or dry eyes), a virus, or a migraine (light sensitivity is one of the most common symptoms of migraines). It could also be caused by something more serious such as an eye condition like a corneal abrasion, a detached retina, uveitis or iritis or a systemic disease like meningitis or encephalitis. Light sensitivity is also a side effect of refractive surgery (such as LASIK) and some medications (such as tetracycline and doxycycline).

How to Deal with Photophobia in Ft Lauderdale

The most effective way to reduce the discomfort caused by photophobia is to stay out of sunlight and dim indoor lights as much as possible while you are experiencing symptoms. Wearing dark sunglasses and keeping your eyes closed may also provide some relief.

In the summer it is more common for UV to trigger corneal inflammation (keratitis) and cause photosensitivity as well. Wind and eye dryness can also set off photosensitivity, which are more good reasons to wear sunglasses.

If the sensitivity is new and the cause is unknown, you should seek medical attention immediately, especially if you experience any of the following symptoms:

  • Blurry vision
  • Burning or pain in the eye
  • Fever and chills
  • Confusion and irritability
  • Severe headache
  • Drowsiness
  • Stiff neck
  • Nausea and vomiting
  • Numbness
  • Foreign body sensation

In cases where the photophobia is a symptom of an underlying issue, treating the issue will likely cause relief in your sensitivity. This will vary depending on the ailment but could include pain medications, eye drops or antibiotics, or anti-inflammatory medications. If the sensitivity is mild due to your genetic predisposition or a result of surgery, make sure you take your sunglasses every time you leave the house. People who wear prescription eyeglasses may consider photochromic lenses which automatically darken when exposed to light.

If you are uncomfortable, speak to your eye doctor in Ft Lauderdale about the best options for your condition.

Are You Missing Your Child’s Hidden Vision Problem?

Your child may show every sign of good eyesight including the ability to see objects in the distance, however that doesn’t necessarily mean that he or she doesn’t have a vision problem.

Amblyopia is one common eye condition that is often hidden behind the appearance of good eyesight.

Also known as “lazy eye” it usually occurs when the brain begins to ignore the signals sent by one eye, often because that eye is weaker and doesn’t focus properly. Sometimes it can occur in both eyes, in which case it’s called bilateral amblyopia. This eye condition is especially common in preemies, and tends to run in families as well, so it’s important to provide your eye doctor with a complete medical and family history.

There are several factors that can cause amblyopia to develop. These include:

  • astigmatism,
  • high nearsightedness or farsightedness,
  • congenital cataract (clouding of the lens of the eye),
  • strabismus (where the eyes are misaligned or “cross-eyed”)

However in many cases of amblyopia there may be no obvious visible structural differences in the eye. In addition to the fact that the eyes may look normal, vision often appears fine as the brain is able to compensate for the weaker eye by favoring the stronger one. Because of this, many children live with their eye condition for years before it is diagnosed. Unfortunately, as a person ages, the brain loses some of its plasticity (how easy it is to train the brain to develop new skills), making it much harder – if not impossible – to treat amblyopia in older children and adults. That’s why it’s so important for young children to have a thorough eye exam.

Are There Any Signs of Amblyopia?

If you notice your child appears cross-eyed, that would be an indication that it’s time for a comprehensive eye exam to screen for strabismus and amblyopia development.

Preschoolers with amblyopia sometimes show signs of unusual posture when playing, such as head tilting, clumsiness or viewing things abnormally close.

However, often there are no signs or symptoms. The child typically does not complain, as he or she does not know what normal vision should look like. Sometimes the condition is picked up once children begin reading if have difficulty focusing on the close text. The school nurse may suggest an eye exam to confirm or rule out amblyopia following a standard vision test on each eye, though it might be possible to pass a vision screening test and still have amblyopia. Only an eye doctor can make a definitive diagnosis of the eye condition.

So How Do You Know If or When To Book a Pediatric Eye Exam?

Comprehensive eye and vision exams should be performed on children at an early age. That way, hidden eye conditions would be diagnosed while they’re still more easily treatable. An eye exam is recommended before entering first grade. The eye doctor may need to use eye drops to dilate the pupils to confirm a child’s true refractive error and diagnose an eye condition such as amblyopia.

Treatment for Amblyopia

Glasses alone will not completely correct vision with amblyopia in most cases, because the brain has learned to process images from the weak eye or eyes as blurred images, and ignore them. There are several non-surgical treatment options for amblyopia. While your child may never achieve 20/20 vision as an outcome of the treatment and may need some prescription glasses or contact lenses, there are options that can significantly improve visual acuity.

Patch or Drops

In order to improve vision, one needs to retrain the brain to receive a clear image from the weak eye or eyes. In the case of unilateral amblyopia (one eye is weaker than the other), this usually involves treating the normal eye with a patch or drops to force the brain to depend on the weak eye. This re-establishes the eye-brain connection with the weaker one and strengthens vision in that eye. If a child has bilateral amblyopia, treatment involves a regimen of constantly wearing glasses and/or contact lenses with continual observation over time.

Your eye doctor will prescribe the number of waking hours that patching is needed based on the visual acuity in your child’s weak eye; however, the periods of time that you chose to enforce wearing the patch may be flexible. During patching the child typically does a fun activity requiring hand eye coordination to stimulate visual development (such as a favorite video game, puzzle, maze etc) as passive activity is not as effective.

The earlier treatment starts, the better the chances are of stopping or reversing the negative patterns formed in the brain that harm vision. Amblyopia treatment with patches or drops may be minimally effective in improving vision as late as the early teen years (up to age 14) but better results are seen in younger patients.

Vision Therapy

Many optometrists recommend vision therapy to train the eyes using exercises that strengthen the eye-brain connection. While success rates tend to be better in children, optometrists have also seen improvements using this occupational therapy type program to treat amblyopia in adults.

The key to improvement through any non-surgical treatment for amblyopia is compliance. Vision therapy exercises must be practiced on a regular basis. Children that are using glasses or contact lenses for treatment, must wear them consistently. Your eye doctor will recommend the schedule of the patching, drops, or vision therapy eye exercise and the best course of treatment.

Amblyopia: Take-home Message

Even if your child is not showing any signs of vision problems, and especially if they are, it is important to have an eye examination with an eye doctor as soon as possible, and on a regular basis. While the eyes are still young and developing, diagnosis and treatment of eye conditions such as amblyopia are greatly improved.

Bifocal and Multifocal Contact Lenses

If you are over 40 and have difficulty seeing close up, you probably have a common age-related condition called presbyopia which is when the eye’s natural lens loses the ability to focus on close objects. Presbyopia is a natural process that occurs as the eye ages and affects the majority of people from age 40 and upward. Individuals with presbyopia are often familiar with the need to hold reading materials such as newspapers an arm’s length away from their eyes in order to see clearly, yet reading glasses with bifocal or multifocal (such as progressive) lenses can help.  

Fortunately for those who don’t like the look, feel or inconvenience of reading glasses, there is another option. Bifocal and multifocal lenses are also available in contact lenses in both soft and Rigid Gas Permeable (RGP) varieties.    

Multifocal contact lenses give you added freedom over glasses and they allow you to be able to view any direction – up, down and to the sides – with similar vision. People wearing progressive lenses in glasses on the other hand have to look over their glasses if they want to view upwards or into the distance.

Multifocal contact lenses are generally designed in one of two ways, as either simultaneous vision lenses or alternating vision lenses.

Simultaneous Vision Lenses 

The most popular version of multifocal contact lenses, simultaneous vision lenses present the distance and near vision zones of the lens at the same time. Typically after a short adjustment period your eyes learn to utilize the segment of the lens that they need to focus on the desired object and essentially ignore the other. 

Translating or Alternating Vision lenses

Similar to bifocal eyeglass lenses, these contacts are divided into distinct areas or zones and your pupil will move to the desired zone depending on your vision needs. Typically the top of the lens, which is what you look through when looking straight ahead is for distance vision and the bottom area (what you look through when you look down) is for near vision. However, this can be reversed according to unique vision needs. 

An Alternative Option to Multifocal Contact Lenses: Monovision

Monovision is another contact lens alternative for presbyopia particularly if you are having difficulty adapting to multifocal lenses.  Monovision splits your distance and near vision between your eyes, using your dominant eye for distance vision and your non-dominant  eye for near vision. 

Typically you will use single vision lenses in each eye however sometimes the dominant eye will use a single vision lens while a multifocal lens will be used in the other eye for intermediate and near vision. This is called modified monovision.  Your eye doctor will perform a test to determine which type of lens is best suited for each eye and optimal vision. 

Are Contact Lenses Right for You?

If you have presbyopia, contact lenses may be a great option for you. Many people prefer the look and convenience of contact lenses over traditional reading glasses. Speak to your eye doctor about the options available to you.

Workplace Eye Wellness: The Dangers of Blue Light

woman 20with 20laptop

When people think of workplace dangers to the eyes, it is usually machinery, chemicals or construction materials that come to mind.  However, a growing danger to the eyes is one that may be less obvious – exposure to blue light from digital devices, television and computer screens and artificial lighting.  

While the long-term effects of blue light or high-energy visible (HEV)  light emission are not yet fully known, what is known is that blue light is a cause of computer vision syndrome (CVS) and sleep disruptions.  60% of people spend more than 6 hours a day in front of a digital device and 70% of adults report some symptoms of computer vision syndrome (CVS) which include eyestrain, headaches, blurred or double vision, physical and mental fatigue, dry or watery eyes, difficulty focusing, sensitivity to light, or neck, shoulder or back pain (caused by compromised posture to adjust to vision difficulty). Most people do nothing to ease their discomfort from these symptoms because they are not aware of the cause. 

In its natural form, blue light from the sun is actually beneficial to your body by helping to regulate your natural sleep and wake cycles – also known as your circadian rhythm.  It can also boost your mood, alertness and overall feeling of well-being. However, prolonged exposure to artificial sources of blue light, such as that found in electronic devices, television and energy-efficient fluorescent and LED lights, has been shown to cause disruptions in the circadian rhythm as well as more serious vision problems. Researchers at Harvard University have linked blue light with damage to the retina at the back of your eyes, indicating that long-term exposure to blue light could be linked to age-related macular degeneration (AMD) and possibly other serious health and vision problems. 

Since 43% of adults work at jobs that require prolonged use of a computer, tablet or other digital monitor, blue light is an increasingly serious threat to your vision, health and productivity. There are a number of options for reducing your exposure to blue light which include computer glasses, specialized lenses and protective coatings. Speak to our eye care professionals to determine which option is best for you.

  • Single Vision Computer Glasses: Provide the optimum lens power and field of view for viewing your computer screen without straining or leaning in to reduce symptoms of CVS. These are ideal for when the computer is at a fixed working distance, and work well if the user needs to view multiple screens at the same working distance.
  • Office Lenses or Progressive Lenses: No-line multifocal eyewear that can be made to correct near, intermediate and some distance vision with a larger intermediate zone for computer vision if indicated. Perfect for those with presbyopia which is the gradual loss of focusing ability that occurs naturally with age. Office lenses work like progressive lenses but provide a wider field of view for intermediate (1-3 m) viewing distance and near working distance (about 40 cm). 
  • Blue-Blocking Lenses: Definitely recommended for this electronic age, blue-blocking lenses block blue light emitted from computer screens that is associated with glare, eye strain and possible sleep disturbances. 
  • Anti-glare and filtering coatings (treatments): Eliminate reflections from the surfaces of your lens to reduce eye strain and discomfort from glare. Some coatings can also block blue light emitted from computer screens. 

While all of these are good options for protecting your eyes, the 20/20/20 rule still applies – after every 20 minutes of near tasks, look at something beyond 20 feet away for at least 20 seconds…it’s a good time to stretch the rest of the body too. 

Additionally, diets high in lutein and zeaxanthin, which are carotenoids found in dark, leafy green vegetables like spinach and kale are protective to blue light damage.

A note about children and blue light:

Children are more prone to blue light damage than adults because the natural lenses in their eyes are so clear that blue light passes easily through to reach the retina.  Adults are somewhat less prone since the older we get our natural lenses become more cloudy and blue light does not pass through quite as easily. Pediatricians recommend that young children under the age of two should get ZERO screen time.   They have much better ways of developing their eyesight with activities requiring hand eye coordination with high contrast physical objects.

Technology is advancing the world, and our jobs and daily lives will only continue to rely upon it. Don’t let technology get in the way of your vision and your health. Ask us about the best solution for you. 

How to Find the Right Pair of Glasses for your Child

glassesondogs

Whether you are looking for regular prescription glasses, sunwear or protective sports eyewear, it can be tough choosing the best eyewear for children and teens. On the one hand, they need to be comfortable and provide the optimal fit for improved vision and protection. At the same time, they also need to be durable, especially if your child is active, plays contact sports or tends to drop or lose things. Not to mention, particularly once you get into tween and teenage years, they have to be stylish and look good. When you add in a budget and your child’s opinion, the decision can be truly overwhelming.

Before you begin looking, it is best to narrow down your options by answering the following questions (and consulting your eye doctor when necessary):

  1. Does my child need to wear his or her glasses all the time or are they for part time wear?
  2. Does my child’s prescription call for a thicker or wide lens requiring a certain type of frame?
  3. Does my child have any allergies to frame materials?
  4. What type of sports protection does my child need?
  5. Would cable (wrap around) temples or a strap be necessary for my child (particularly in toddlers)?
  6. Do I have a preference in material or features (such as flexible hinges or adjustable nose pads)?
  7. Are there particular colors or shapes that my child prefers or that will look most attractive?

Armed with the answers to those questions and a qualified optician, you can begin your search. Keep the following tips in mind:

  1. Including your children in the selection process will greatly enhance the chances of them actually being excited about wearing and caring for their glasses. So make it fun and exciting for them!
  2. Polycarbonate or Trivex lenses are impact-resistant lenses that are recommended for children’s eyewear to protect their eyes. Also consider adding a scratch resistant coating.
  3. When trying on options, consult with the optician to ensure proper fit. Make sure the frames don’t slide off the bridge of the nose, cover the eyes, squeeze at the temples or extend too far behind the ears. Proper frame fit is especially important for kids with specialty prescriptions like bifocals or Myovision, and for kids with lazy eye (amblyopia) and high spectacle Rx.
  4. If shopping for protective sports eyewear, consider the conditions of the sport your child plays to ensure proper eye protection. They now have much more selection in children’s safety eyewear with cool designs and some glasses even have convertible temples (arms) and straps to become interchangeable dress wear and safety wear.
  5. Keep in mind that it may be more cost effective to spend a little more on strong and durable eyewear now than to have to replace a flimsy pair later. Each office differs in the warranties they offer and the length and terms of coverage. Ask your optician about what is and is not covered under their frame and lens coverage policy.
  6. If your child is put into bifocal lenses for reading issues or poor focusing issues (commonly used in pediatric vision therapy) they will generally require a deeper frame in order to have enough room for the bifocal, which is often difficult when dealing with smaller frames.
  7. Consider a blue light protecting anti-reflective coating. Children are especially prone to damage from blue wavelengths of light because their human lenses are so clear. Blue light is emitted from many of the devices we use such as cell phone screens, tablets, laptops, TVs, and the sun as well.

The great news is that the options in children’s eyewear in terms of style, quality and innovation is progressing rapidly. Rather than dreading the eyewear shopping experience, have a positive attitude. This will have a positive influence on your child’s relationship to eyewear and good vision that can last a lifetime.

Preventing Age-related Macular Degeneration

dad riding bike with daughter

February is AMD and Low Vision Awareness Month in the United States, and it’s White Cane Week in Canada. Age-related Macular Degeneration (AMD) is a leading cause of vision loss in adults aged 50 and older. Awareness about the disease, the risk factors and prevention are critical, even for younger generations because taking care of your eyes while you are young will help to reduce the risks later on in life.

Understanding AMD

AMD is a disease that damages the macula, which is the center of the retina responsible for sharp visual acuity in the central field of vision.  The breakdown of the macula eventually results in the loss of central vision and can occur in one eye or both eyes simultaneously. While AMD doesn’t result in complete blindness, the quality of vision is severely compromised leading to what we refer to as “low vision”.

The loss of central vision can interfere with the performance of everyday tasks such as driving, reading, writing, cooking, or even recognizing faces of friends and family.  The good news is, there are many low vision aides on the market now that can assist in helping you to perform these tasks. 

There are two types of AMD, wet and dry.

Dry AMD is the most common form of the disease. It is characterized by blurred central vision or blind spots, as the macula begins to deteriorate. Dry AMD is less severe than the wet form, but can progress to wet AMD rapidly.

Wet AMD is when abnormal blood vessels begin to grow under the retina and leak fluid and blood into the macula, causing distortions in vision. Wet AMD can cause permanent scarring if not treated quickly, so any sudden blur in vision should be assessed immediately, especially if one is aware that they have AMD.

Are You at Risk?

The biggest risk factor for AMD is age. Individuals over 60 are most likely to develop the disease however it can occur earlier.  Additional risk factors include:

  • Smoking: According to research smoking can double the risk of AMD.
  • Genetics and Family History: If AMD runs in your family you are at a higher risk. Scientists have also identified a number of particular genes that are associated with the disease.
  • Race: Caucasians are more likely to have AMD than those from Hispanic or African-American descent.
  • Lifestyle: Obesity, high cholesterol or blood pressure, poor nutrition and inactivity all contribute to the likelihood of getting AMD. 

Prevention of AMD:

If you have risk factors, here is what you can do to prevent or slow the progression of AMD:

  • Regular eye exams; once a year especially if you are 50 or over.
  • Stop smoking.
  • Know your family history and inform your eye doctor.
  • Proper nutrition and regular exercise: Research indicates that a healthy diet rich in “Eyefoods” with key nutrients for the eyes such as orange peppers, kale and spinach as well as regular exercise may reduce your risks or slow the progression of AMD.
  • Maintain healthy cholesterol levels and blood pressure. 
  • Dietary supplements: Studies by the National Eye Institute called AREDs and ARED2 indicated that a high dosage of supplements of zinc, vitamin C, vitamin E and lutein may slow the progression of advanced dry AMD (it is not recommended for those without AMD or early AMD).  Speak to a doctor before taking these supplements because there may be associated risks involved. 
  • Wear 99% -100% UV-blocking sunglasses.

The first step to eye health is awareness. Help us to spread the word about this debilitating disease and the importance of choosing a healthy lifestyle.

Resolve to Prevent Glaucoma in 2016

Glaucoma 20Eye 20Diagram

This year, make healthy eyes and vision your resolution. Find out if you or a loved one is at risk for glaucoma, and take steps for prevention.

Glaucoma is a leading cause of preventable vision loss and blindness in adults in the United States and Canada and the second leading cause of blindness in the World. Projections show that the number of people with the disease will increase by 58% by 2030. These facts however could change with proper awareness.

When detected in the early stages, glaucoma can often be controlled, preventing severe vision loss and blindness. However, symptoms of noticeable vision loss often only occur once the disease has progressed. This is why glaucoma is called “the sneak thief of sight”. Unfortunately, once vision is lost from the disease, it usually can’t be restored.

Risk Factors

Prevention is possible only with early detection and treatment. Since symptoms are often absent regular eye exams which include a glaucoma screening are essential, particularly for individuals at risk for the disease. While anyone can get glaucoma, the following traits put you at a higher risk:

  • Age over 60
  • Hispanic or Latino descent, Asian descent
  • African Americans over the age of 40 (glaucoma is the leading cause of blindness in African Americans, 6-8 times more common than in Caucasians.)
  • Family history of glaucoma
  • Diabetics
  • People with severe nearsightedness
  • Certain medications (e.g. steroids)
  • Significant eye injury (even if it occurred in childhood)

What is Glaucoma?

Glaucoma is actually a group of eye diseases that cause damage to the optic nerve due to an increase in pressure inside the eye or intraocular pressure (IOP). Treatments include medication or surgery that can regulate IOP and slow down the progression of the disease to prevent further vision loss if detected early. The type of treatment depends on the type and the cause of the glaucoma.

What are the Symptoms?

Most times glaucoma does not have symptoms. There is no pain unless there is a certain type of glaucoma called angle closure glaucoma. In this case, the channel of outflow gets crowded then blocked, causing foggy, blurred vision, halos around lights, headache and even nausea. This is a medical emergency and should be assessed immediately as the intraocular pressure can become extremely high and cause permanent damage within hours.

Most forms of glaucoma have an “open angle”, which is not so urgent, but does need compliance with the treatment plan (which is sometimes difficult as some of the glaucoma drops have uncomfortable side effects). Once vision loss develops it typically begins with a loss of peripheral or side vision and then progresses inward.

What Can You Do To Prevent Glaucoma?

Because there are no symptoms, regular eye exams are vital to early detection. If you have any of the above risk factors or you are over 60, make a yearly comprehensive eye exam part of your routine. Make sure that your eye doctor knows your family history and any risk factors that are present.

A comprehensive eye exam can determine your risk of developing glaucoma; if you have been diagnosed with glaucoma and have concerns about your treatment, it is best to speak openly with your doctor. Remember, a simple eye doctor’s appointment on a regular basis could save your vision for a lifetime.

Why Do We Need Glasses?

The most well-known part of a comprehensive eye exam is the basic vision test. When you have a general vision test, one of the main conditions the eye care practitioner is checking for is a refractive error. A refractive error means there is an abnormality in the shape of the eye, changing the eye’s ability to focus light directly onto the retina.This causes blurred vision and can usually be corrected by wearing prescription eyeglasses, contact lenses and possibly, alternate treatments such as vision therapy, ortho-k, LASIK or refractive surgery such as LASIK.

 

The term, “refractive error” refers to a problem with the process of refraction that is responsible for sight. Normally, light rays that enter your eye are refracted or bent through the cornea and the lens, and ultimately converge or are focused onto a single point on the retina. From the retina, messages are sent through the optic nerve to the brain which then interprets these signals into the image that we are seeing.   

 

In order for this process to work effectively, the anatomy of the eye including the length of the eye and the curvature of the cornea and the lens must be just right to be able to focus the light onto the retina. When this is not the case, a refractive error will occur.

 

There are several different types of refractive errors, depending on which part of the eye is affected, and it is possible to have multiple refractive errors at the same time:  

 

Myopia or nearsightedness:

In myopia the length of the eyeball is too long which results in light coming to a focus in front of the retina, rather than on the retina. This allows the individual to see well when objects are close but not clearly when looking at objects at a distance.

 

Hyperopia or farsightedness:

Hyperopia is when the eyeball is shorter than normal and can result in near objects being blurry. However, people experience hyperopia differently. Sometimes distant objects are clear while other times people may experience overall blurred vision near and far or no problems at all. In children particularly, the lens may accommodate for the error allowing for clear vision but may cause fatigue and sometimes crossed eyes or strabismus. Hyperopia causes eyestrain or fatigue especially when looking at near objects for a period of time. Often people with 20/20 vision may still need glasses at their desk to relax their eyes and improve concentration.

 

Astigmatism:

Astigmatism is usually the result of an irregularly shaped cornea (although it can sometimes also be due to a misshapen lens). The cornea, which is normally round, is more football-shaped in an eye with astigmatism, resulting in multiple focus points either in front of the retina or behind it (or both). People with astigmatism usually have blurred or distorted vision to some degree at all distances, near and far.

 

Presbyopia:

Presbyopia is an age-related condition which usually begins to appear sometime after 40.  As the eye begins to age, the lens stiffens and can no longer focus clearly on objects that are close.  

 

It’s important to note that presbyopia is often confused with hyperopia, as both cause problems focusing at near distances.  However, high hyperopia can also cause blur at far distances as well, especially in dim lighting, and depth perception problems can result in motor vehicle accidents.  In these instances people with hyperopia could use glasses at any distance.

If you are having trouble seeing, it is important to have an eye exam to determine the cause of the problem and to effectively correct your vision. Even if your vision is fine, you should schedule a routine eye exam on a regular basis to ensure that your eyes are healthy and that any potential problems are caught early.

 

All About Dry Eyes

Sometimes a person is unable to produce enough tears or their tears do not possess the right qualities to keep eyes healthy and comfortable. This can cause a consistent lack of sufficient lubrication and moisture on the surface of the eye, known as dry eyes.
 
Normally, the eye constantly lubricates itself with tears by producing them at a slow and steady rate, keeping itself moist and comfortable. Usually these tears consist of three layers, an oily, a watery, and a mucus layer. Each layer has a specific role in lubricating your eyes. The oily layer is outermost. It's main purpose is to slow evaporation of the tear. The watery layer is in the middle. This makes up the majority of what a person normally thinks of as tears. This layer cleans the eye and helps to wash away small foreign objects and particles. The inner layer consists of mucus. This mucus allows the watery layer to stick to the eye and spread evenly over the eye in order to keep it lubricated. In a person with dry eyes, either hormonal changes, side effects from medication or some other factor causes the eye to either not produce enough tears, or leave out parts of the tear that make proper lubrication possible.
 
Dr. George Fournier, of Ft. Lauderdale Eye Associates in Ft. Lauderdale, Florida explains, “Symptoms of dry eyes include stinging or burning in the eyes, scratchiness, and excessive irritation from smoke or wind. Although it may sound counter-intuitive, the eyes' response to the consistent irritation caused by dry eyes may also cause a person to experience excessive tearing. In this case, the eye is attempting to flush and lubricate itself by producing more tears, but is unable to do so successfully due to the rate of evaporation or inability to spread the tears properly.”
 
Although dry eyes are not always curable, your optometrist may prescribe artificial tears to help with some of the symptoms. Artificial tears are lubricating eye drops that may help with dry, scratchy feeling eyes. Different artificial tears work in different ways. Some help replenish parts of the tear that your eyes are not producing on its own, others help to produce more tears overall. Your eye doctor will assist you to choose which will help you most. Dr. Fournier cautions, however, “These artificial tears should not be confused with eye drops that are advertised to 'get the red out.' These eye drops may indeed reduce the appearance of redness in your eyes, but this is accomplished by making the blood vessels in your eyes smaller rather than actually lubricating your eyes. As such, these drops can sometimes actually make your symptoms worse. One should also be aware that if you wear contacts, some eye drops require you to take them out before using the drops and wait 15 minutes or more before reinserting your contact lenses.”
 
Some cases of dry eyes are seasonal, such as those which occur as a result of cold, dry winter air. In this case, your eye doctor may recommend wearing sunglasses or goggles when outdoors to reduce your eyes' exposure to the sun, wind and dust. For indoors, your optometrist may recommend an air cleaner and humidifier to take dust out of the air and add moisture to air which is too dry.
 
Studies have also shown that nutrition may have a part in helping to relieve some symptoms of dry eyes. Your eye doctor may recommend nutritional supplements such as omega-3. Good sources of omega-3 fatty acids are cold-water fish, cod, herring and salmon, as well as flaxseed oil. Mild dehydration can make symptoms worse too, so be sure to drink plenty of water, 100 percent fruit and vegetable juices and milk.
