Pink eye or conjunctivitis is a very common eye condition. That, in addition to dry eyes, is what our Plano patients tend to complain about the most when coming into our eye clinic. Many of these patients want to know, can I wear my contact lenses with pink eye or dry eyes?

The problem is that the contact lenses tend to “suffocate” the eye. When your eyes are suffering from an eye condition, they are more sensitive and that in turn can lead to a scratched cornea. This is especially true should you feel the need to always rub your eyes.

The good news is that if you suffer from pink eye or dry eyes, not all hope is lost. There are different contact lens brands on the market that are geared towards those whose eyes tend to dry out as they wear contact lenses. We recommend daily contact lenses as they offer the ability to wear a fresh pair of lenses on a daily basis. Acuvue Oasys and Alcon Dailies Total 1 are daily lenses that offer the user a lens that is more moist and better for those with dryness issues. Some patients opt for gas permeable lenses that retain more water.

There are various options on the market for contact lenses for those suffering from dry eyes or pink eye. If you fear you have or will scratch your cornea, it is always best to err on the side of caution and call us at 972-985-3638 to check it out. We can also discuss the best contact lens brand available for you.

Age-related macular degeneration is a serious condition that can threaten your vision and general well-being. Characterized by the deterioration of the central area of the retina called the macula which is responsible for focused vision, the disease gradually reduces your central vision. This affects the ability to see fine details, recognize faces, read, drive, watch television and even use a computer. The disease often leaves some vision resulting in a condition called low vision, which is considered a form of legal blindness.

AMD is the leading cause of vision loss in the older population and the numbers are expected to increase as Americans and Canadians continue to live longer.

What causes AMD and how can it be prevented?

As you can see by the name, the primary risk factor of AMD is age, particularly over age 50. Caucasian women are the most common demographic to be hit with this ocular disease; family medical history and having lighter colored hair, skin and eyes play a large role as well. However, several lifestyle factors have been shown to cause an increase in AMD development; so there may be ways to reduce your risk, even if you have a genetic predisposition.

In fact, most of the controllable risk factors pose general health risks that cause a plethora of health issues, so addressing them will boost your overall health and wellness, in addition to protecting your eyes and vision from AMD. Here are 6 ways to prevent AMD and the vision loss that accompanies it:

1. Stop Smoking

Smoking, and even living with a smoker, have been shown to significantly increase your risks of developing AMD to between 2-5 times the risk of non-smokers! If you also have a hereditary risk, smoking compounds that risk tremendously.

2. Get Active

Studies show that obesity and a sedentary lifestyle increase the risk of advanced macular degeneration that leads to significant vision loss. Maintaining a healthy weight and being active can reduce your risk. That could be as easy as regular walking, at least 3 times a week for 30 minutes.

3. Control Blood Pressure

Since the eye contains many tiny blood vessels, high blood pressure can have a serious impact on the health of your eyes. Have your blood pressure checked by your doctor and follow any medical advice you are given to reduce high blood pressure, whether that includes diet, exercise or medication.

4. Choose a Healthy Diet

A diet rich in antioxidants has been shown to protect against AMD. Antioxidants can be found in abundance in dark green leafy vegetables such as spinach, broccoli, kale and collard greens, as well as orange fruits and vegetables such as peppers, oranges, mango and cantaloupe. Eating a wide range of fresh fruits and vegetables, 5-9 servings a day, as well as fish, which contain Omega-3, and avoiding sugar and processed foods will help to keep your body healthy in many ways, including reducing your risk of AMD.

5. Use UV and Blue Light Protection

Long-term exposure to UV rays from the sun and blue light (from digital devices among other things) have been linked to AMD. Make sure you wear sunglasses every time you are exposed to sunlight and wear blue light blocking glasses when you are viewing a digital device or computer for extended periods of time.

6. Take Supplements*

Certain nutritional supplements have been shown to slow the progression of AMD and the vision loss that accompanies it. This formula of supplements was developed from a 10 year study of 3,500 people with AMD called the Age-Related Eye Disease Study (AREDS) and its successor AREDS2. It is not recommended to take supplementation as a preventative measure but rather only if you are diagnosed with intermediate or advanced AMD.

*Speak to your eye doctor before you make a decision about this option.

During your yearly comprehensive eye exam, your eye doctor will screen for early signs of AMD and recommend treatment if it’s detected. If you’re at greater risk – because of your age or a family history of AMD / blindness of unknown cause, for example – additional testing may be necessary.

AMD can be a devastating disease. If you are aware that you are at risk, it is worthwhile to do everything you can to prevent it and the vision loss that it can bring. Take the time to understand AMD and do what it takes to lower your chances of knowing its effects first-hand.

January is Glaucoma Awareness Month

Make your resolution for healthy vision this year by knowing the risks and signs of glaucoma.

As the leading cause of blindness worldwide, glaucoma has earned the nickname “The Sneak Thief of Sight”. This is because often there are either no symptoms or a sudden onset of serious symptoms that can quickly lead to vision loss if not treated.

Glaucoma-related vision loss is usually caused by optic nerve damage due to elevated pressure within the eye (intraocular pressure). The damage cannot be reversed however there is treatment for glaucoma, particularly when it is caught early before nerve damage has occurred.

While anyone can develop glaucoma (children are sometimes even born with it) there are risk factors that increase the chances of developing the disease. These include:

• Age over 60 (over 40 for African Americans)
• Family history of the disease
• High eye or blood pressure
• African American, Japanese, or Hispanic descent
• Previous eye injury or surgery
• Diabetes
• History of corticosteroid treatment
• Severe myopia (nearsightedness) or hyperopia (farsightedness)

Known measures to help prevent glaucoma or reduce the risks include maintaining a healthy diet and weight, regular exercise, refraining from smoking and protecting your eyes from UV exposure. Controlling blood pressure is also beneficial.

Types of Glaucoma

There are two main types of glaucoma, open-angle and angle-closure, with open-angle being the most common and accounting for approximately 70-90% of cases. Open-angle refers to chronic cases of the disease that progress slowly over time, and are usually caused by high intraocular pressure. Angle-closure glaucoma can be chronic or acute and is often caused by an inherited condition or the result of an injury to the eye.

While each of these types of glaucoma has subtypes the major differences between them have to do with the way the disease affects the eye and the symptoms. While open-angle often has no early symptoms yet may eventually cause loss of peripheral vision, angle-closure glaucoma is often characterized by more obvious signs such as blurred vision, pain, headaches, tunnel vision, halos that appear around lights and even nausea and dizziness. These symptoms can be a medical emergency and must be treated immediately.

Detecting Glaucoma

Since there are often no symptoms as glaucoma develops, regular glaucoma screenings are key to early diagnosis and treatment. Such screenings should include an exam of the optic nerve, measuring the inner eye pressure and visual field screenings. Some cases of glaucoma occur with normal or even low eye pressure (low tension glaucoma) and therefore people should not rely on any vision screenings where all they do is an “airpuff” test.

Newer technologies such as OCT, can painlessly scan the optic nerve and determine if there is glaucomatous damage even earlier than visual field tests or other exams might show.

Treatment for Glaucoma

While vision that is lost from glaucoma’s damage to the optic nerve can’t be restored, the eye can be repaired (and intraocular pressure returned to normal) to prevent further damage and loss. Treatments include eye drops and surgery, depending on the type of glaucoma, the cause and the severity of the disease.

If you have been diagnosed with glaucoma and prescribed eye drops, it is important to keep using the eye drops as directed even if the drops irritate your eyes or you do not notice improvement in vision. The eye drops prevent eye pressure spikes that can damage the optic nerve. Since the vision loss from glaucoma is not reversible, if you have concerns with the eye drops, ask your eye doctor to try out a different brand instead.

Childhood eye injuries, such as a ball hit or puncture, particularly one which altered the internal structures of the eye or allowed fluid to flow out of the eye can cause problems later in life. Glaucoma that results from such long-forgotten injuries may not be detected until years after the injury, so it is important to have routine eye checkups if you have ever sustained an eye injury.

The best way to protect your eyes and vision from this devastating disease, especially if you have heightened risk factors, is to ensure you have regular comprehensive eye exams to look for signs of glaucoma inside the eye. Since symptoms often don’t appear until damage is done, the best course of action is preventative.

If you have any of the risk factors listed above, when you come in for your yearly comprehensive eye exam, speak to your eye doctor about glaucoma and what you can do to prevent it.

Nerf guns or blasters come in a remarkable number of shapes and sizes and have become incredibly popular for use in the home and even in large scale “Nerf Wars”.  However publicity surrounding the toy has not been all positive.  Many parents out there are questioning the safety of the toy foam guns, particularly to the eyes, before making the purchase.

The question of safety ultimately comes down to the user.  Nerf darts are relatively soft, foamy and not inherently dangerous, but if shot in the wrong way, they could cause pain or even serious injury. This is particularly true of the eyes because they are a vulnerable organ that can be damaged easily upon impact. Injuries from even a soft projectile could include corneal abrasions (surface scratches), bleeding, cataracts and even retinal detachment which can lead to permanent vision loss. 

Nevertheless, Nerf guns are fun and can even be used to help motor development and other skills, so with the right guidelines, children can learn to use them safely and benefit from the enjoyment they provide. 

Want surefire eye safety? Wear safety glasses!

The best defense for your eyes is safety glasses.  This is the one way you can be sure that you or your child’s eyes are truly safe during Nerf shooting.  We strongly recommend safety glasses be worn during any play that involves projectile objects, particularly for small children or during serious games such as Nerf Wars.

General rules of Nerf Gun play:

1. Never shoot at the face.
2. Never look into the barrel of the nerf gun, even if you think it isn’t loaded. 
3. Avoid walking around with your finger on the trigger until you are ready to point and aim at the proper target. 
4. Only shoot others that are “playing” and are aware that you are aiming at them.
5. Don’t shoot from a moving vehicle (including a bicycle, skateboard, rollerblades, etc.).
6. Don’t shoot at a moving vehicle.
7. Never shoot at a close range.   
8. Never leave loaded gun in reach of a child or individual that is not able to use the toy properly and safely. 

To be safe, all toy guns that shoot projectiles should be treated as a dangerous toy in order to ensure proper usage and precautions. Yes, Nerf guns can cause serious eye damage and even vision loss, but these type of injuries can be caused by many “harmless” objects as well. Before you purchase a toy like this for your child, ask yourself whether the child is old enough and mature enough to understand the safety issues involved and to be able to use it responsibly.  

Why Are My Eyes So Dry?

Do you experience dry, scratchy, burning eyes, redness or pain, a gritty feeling like something is in your eye? Or perhaps, excessive tearing, blurred vision, eye fatigue or discomfort wearing contact lenses? There could be a number of causes for your symptoms including allergies, reactions to an irritant or medication or an infection. You could also have a chronic condition called Dry Eye Syndrome.

It’s estimated that one out of every eight adults suffers to some extent from dry eye syndrome, which can range from mild to severe. Despite the fact that it is one of the most common eye problems, a surprisingly large percentage of patients are not aware of it.

What is Dry Eye Syndrome?

Your eyes need a layer of tears to lubricate the surface and keep the eyes comfortable, clean and clear. These tears also wash away particles, dust and bacteria that can lead to infection and eye damage. Dry eye syndrome occurs when there is a chronic lack of lubrication on the surface of the eye either because not enough tears are being produced, the quality of the tears is weak or they evaporate too quickly. This causes the common uncomfortable symptoms including:

• Itching
• Burning
• Redness
• Soreness or pain
• Dryness (and sometimes even excessive tearing because the eyes are trying to compensate)
• Light sensitivity
• Eye fatigue
• Blurred vision
• Grittiness or a feeling like there is something in your eye
• Vision seems to change when blinking

Factors that Contribute to Dry Eye Syndrome

There are a number of factors that can increase your risk of suffering from Dry Eye Syndrome. While some of them are inherent, there are some environmental factors that can be changed to reduce your risk or symptoms. Risk factors include:

• Aging: While it can occur at any age, dry eye is more common in individuals over age 50. 
• Women: Likely related to hormonal fluctuations, women are more likely to develop dry eyes than men, especially during pregnancy, menopause or when using birth control pills. 
• Digital screen use: Whether it is a computer, a smartphone or a tablet, when our eyes are focused on a digital screen we tend to blink less, increasing tear evaporation and increasing dryness, blurriness and discomfort. Remember to regularly take a break, look away from the screen and blink several times.
• Medications: A number of medications – both prescription and nonprescription – have been found to cause dry eye symptoms including certain blood pressure regulators, antihistamines, nasal decongestants, tranquilizers and antidepressants. 
• Contact lenses: Dry eyes is a common problem in contact lens wear. Several manufacturers have started offering lenses that hold more moisture to combat this common issue. 
• Dry air: Whether it is the air conditioning or forced-air heating inside or the dry, windy climate outside, the environment of the air around you can contribute to dry eyes by causing your tears to evaporate too quickly. 
• LASIK: One side effect of LASIK and other corneal refractive surgery is dry eyes, which usually lasts about 3-6 months and eventually resolves itself. 
• Eyelid conditions: Certain conditions which prevent the eyelid from closing completely when sleeping or even blinking can cause the eye to try out.
• Allergies or infections: Chronic inflammation of the conjunctiva which is often caused by allergies or infections such as Blepharitis can result in dry eyes. 
• Systemic diseases: People with autoimmune diseases or systemic conditions such as diabetes, thyroid disease, Sjogren’s syndrome, rheumatoid arthritis and lupus are also more prone to Dry Eye. 

How do you treat dry eye symptoms?

If you have dry eyes, you don’t need to suffer. There are a number of treatment options that can help, depending on the severity and cause of your condition, which can reduce symptoms and enhance your comfort.

Treatments for dry eyes can include non-prescription or prescription eye drops, omega 3 supplements, special lid therapies, punctal plugs, ointments, different contact lenses, goggles or ergonomic changes to your work station. Speak to your eye doctor to discuss the cause of your dry eye and the best remedy for you. Even when it comes to the seemingly straightforward treatments like over-the-counter eye drops, they aren’t all the same. Different ingredients are tailored towards different causes of dry eye.

Red, itchy, watery eyes and swollen eyelids (along with sneezing, congestion or a runny nose)… these symptoms are a clear indication that allergy season has arrived. These allergic symptoms are caused by a reaction to allergens, which are substances in the environment that are usually harmless. If, however, you are one of the unlucky that is predisposed to allergies, these substances can illicit a serious and sometimes even debilitating allergic response. 

As opposed to food, medicine, or insect allergies which don’t often affect the eyes, eye allergies are a common symptom of airborne allergens including mold, pollen (from trees and flowers), dust and pet dander. The summer fall and spring are often the worst times for a high pollen count and many individuals suffer during these seasons. 

An allergic eye reaction occurs when your eye releases histamines in an effort to protect itself from a perceived threat (an allergen such as dust, pollen, animal dander, mold spores, eye drops or airborne chemicals). The release of the histamines causes the symptoms of redness, itchiness, burning and tearing. This response is also sometimes known as allergic conjunctivitis. 

The most common type of eye allergies are perennial and seasonal allergic conjunctivitis. Perennial eye allergies are a response to household allergens that exist all year round such as pet dander, mold, or dust mites. Seasonal allergies usually result from pollen from plants, grass and trees that are found in the air and depend on the season and the types of pollens in the environment.  Seasonal allergic conjunctivitis is often more severe than perennial and can cause puffy eyelids and itching which can make symptoms worse. 

The best way to reduce discomfort and prevent an allergic reaction is to stay away from allergens as much as possible. Here are some tips on how to reduce exposure:

• Minimize outdoor exposure during pollen season: 
• Stay inside when pollen counts are particularly high or during a windy day.
• Keep windows closed and use air conditioner with a clean filter.
• Wear sunglasses outside to keep irritants from entering the eyes. 
• Reduce indoor allergens:
• Wash bedding frequently in hot water and use mite-proof covers on pillows, blankets and mattresses. 
• Prevent household mold by reducing humidity and keeping areas that are subject to humidity or dampness (such as bathrooms, kitchens or basements) clean. Use a dehumidifier when necessary and clean any mold you see with bleach. 
• To reduce dust, clean floors and surfaces with a damp rag or mop rather than sweeping or dry dusting. 
• Wash your hands and clothes after coming into contact with animals.
• DO NOT rub your eyes as this can worsen symptoms, greatly aggravating swelling and itchiness, and can sometimes even cause an infection. 

If you have severe allergies, avoid contact lens wear or reduce wear time when allergies flare up, as contact lenses can worsen symptoms and do not fit as they normally would when the eyes are swollen. This is why having back up glasses is so important. Changing to one day single use disposable contacts can also sometimes reduce allergy symptoms.   

There are some steps you can take to alleviate symptoms of eye allergies. Over-the-counter solutions include artificial tears, decongestant eye drops (which shouldn’t be used for longer than a week) or oral antihistamines (which can sometimes worsen symptoms). If no eye drops are available, cool compresses (avoid heat) will also help to reduce the itch.  If these treatments don’t work, you can get a prescription for stronger eye drops (antihistamine or short term steroid drops to reduce symptoms), oral antihistamines or possibly immunotherapy (such as allergy shots).

If you are experiencing symptoms of allergic conjunctivitis, don’t just assume they are allergies. See your eye doctor to determine the cause to ensure that it is not a more serious eye condition. 

Most people wouldn’t consider contact lenses dangerous. In fact, they are a great alternative to glasses, offering convenience and great vision for those who wear them. However, when not obtained and used according to an eye doctor’s instructions, the consequences can be devastating.  

Contact Lenses Need to Fit

Like shoes, one size of contact lens does not fit all. Even daily disposable contact lenses need a proper lens fitting, as lens materials and curvatures vary from one brand to the next. Often patients that complain of contact lenses that feel dry within a couple hours of applying them are actually wearing contact lenses that are not an ideal fit. Many factors can affect a lens fit, including growth, allergies, medications, hormone changes, and others.   Sensitivities to eye drops and cleaning solutions may also affect comfortable contact lens wear.  

The Dangers of Contact Lens Use

We all know how uncomfortable it is when there is a foreign object in our eye. The tearing and watering that occurs as the eye’s natural attempt to remove foreign matter displays the eye’s sensitivity compared to other parts of the body.  Any time a foreign object comes into contact with the eye (even your finger), there is a risk to the eye – and that risk includes contact lenses.  Improper hygiene and useage of contact lenses can scratch the surface or bring bacteria into the eye which can lead to serious infections and permanent damage to the eye and vision.

According to a recent report from the Centers for Disease Control and Prevention, almost 20% of patients that reported infections of the cornea related to contact lenses had a corneal scar, a decrease in visual acuity or needed a corneal transplant as a result of the infection.  Further, 25% of infections involved poor contact lens hygiene, which means they likely could have been prevented.

Dangerous Behaviors that Put Contact Lens Users At Risk

Here are some of the most dangerous contact lens habits that should be avoided to eliminate your risk of eye damage or a potentially blinding eye infection.

• Failing to wash your hands with soap and dry them before applying or removing lenses.
• Rinsing contacts or your lens case with tap water, sterile water or other substances.
• Re-using solution or topping off the solution in your lens case rather than emptying it, cleaning it and refilling it.
• Failing to remove lenses before swimming or entering a hot tub.
• Leaving in contact lenses too long or sleeping in contacts that are not meant to sleep in.
• Failing to follow the wearing schedule prescribed by your eye doctor.
• Using the same lens case for too long (it should be cleaned regularly and replaced around every three months).
• Wearing lenses that are not obtained with a prescription through an eye doctor or legally authorized contact lens distributor.
• Ironically, as you can see, water is one of the biggest dangers for contact lens wearers at it can harbor dangerous bacteria under the lens or in a contaminated lens case.  These dangers can be easily avoided by following your eye doctor’s instructions in handling and wearing your contact lenses.

Cosmetic/Decorative Contact Lenses

With Halloween on the way it’s important to stress that you should ONLY purchase contact lenses from an eye doctor or legally authorized contact lens seller with a prescription. Even if you are purchasing  purely decorative contact lenses with no vision correction, you need a doctor to measure your eye to ensure they fit properly.  Contact lenses are a medical device and it is illegal to sell them without proper authorization. Therefore you should never purchase them from a costume or party store – they are unregulated and could cause serious harm to your eyes and vision.

If you notice any unusual redness, discharge, crusting, light sensitivity or pain, immediately remove your contact lenses and go see your eye doctor as soon as possible. Some serious eye infections can cause permanent vision damage or loss even within a day or two.

While you should not approach contact lens use as a dangerous activity, it is important to understand the importance of proper hygiene and use.  As long as you obtain contact lenses safely and follow the instructions of your eye doctor, contact lenses are a safe, convenient and effective option for vision correction.

90%! That’s the number of sports eye injuries that studies show can be prevented using proper eye protection.  Yet most sports leagues don’t require protective eyewear as part of their uniform or safety requirements.  This leaves it up to athletes, parents and coaches to ensure that proper measures are taken to keep eyes safe during athletic play.

Protective sports eyewear can come in a number of forms depending on the sport, and includes sports glasses or goggles, eye shields and eye guards.  Regular prescription eyeglasses or sunglasses do not protect the eyes and can sometimes cause greater injury if impact is made and lenses or frames are shattered or broken. If you do wear prescription eyewear, there are a number of options including wearing contact lenses with safety eyewear, purchasing prescription safety eyewear or wearing safety goggles over your regular prescription glasses.   

What Makes Safety Eyewear Safer?

Protective eyewear is made of impact resistant lenses from materials such as polycarbonate or trivex, which are much stronger than other types of plastic used to make typical eyewear lenses.  Polycarbonate has a long history of safety eyewear use in adults and children and Trivex is a newer optical material that is lighter than polycarbonate and offers better optical quality.  Both materials have built in ultraviolet protection to protect your eyes from damage from the sun.

Sports frames are also made from strong, impact-resistant materials such as strong plastics or polycarbonates.  They tend to cover larger areas than traditional glasses to protect more of the area around the eye and block dust, sunlight and other elements from entering from the sides or top of the frame. Sports glasses and goggles usually incorporate impact resistant padding to create a cushion between the frame and the face or nose for increased comfort, impact absorption and to prevent slipping.

Some goggles do not fit well under helmets, such as those used in football and lacrosse, so it is wise for athletes to bring in their helmets when shopping for sports eyewear to ensure they fit under the helmet properly.

Although athletes often shy away from wearing sports eyewear due to concerns of reduced performance, in reality they often can improve performance with new innovations in sportswear that offer improved peripheral vision.

Common Sports Eye Injuries

Eye injuries commonly occur in baseball, basketball, racquetball, tennis, badminton, and other sports.  Here are some of the common types of injuries.

• Scratched eye or corneal abrasion – This is when damage occurs to the external surface of the eye and commonly occur from being poked, scratched or rubbed when there is a foreign body present on the surface such as sand or dust.  Corneal abrasions can be very painful, cause redness and sensitivity, particularly to light. Scratched eyes should be treated immediately by a doctor because bacteria can enter through the eye causing serious infections, that can even lead to blindness.
• Blunt trauma/swelling – is when an object, such as a ball or an elbow impact the eye causing swelling or bleeding such as a black eye (in which the eyelids bruise and swell) or a subconjunctival hemorrhage (bleeding from a blood vessel between the white of the eye and the clear conjunctiva). Black eyes may not appear serious but they should be checked out by a doctor to make sure there is no internal damage.
• Traumatic iritis – an inflammation that occurs following an eye injury such as a blunt trauma that affects the color part of the eye that surrounds the pupil. The inflammation should be treated to ensure there is no permanent vision loss.  
• Penetrating injury – injuries that occur when a foreign object enters the eye, causing the eye to rupture, can cause severe damage, swelling and bleeding.  These should be considered a medical emergency and treated immediately.

As you can see, most of these injuries can be prevented simply by wearing proper protection over the eye.  Your vision is essential for playing the sports you love, so don’t put it as risk by failing to protect your eyes properly. With the increasing selection of frames and lenses for safety and sports eyewear at affordable pricing, an active lifestyle can also be safe.
