Smart Hygiene Habits to Care for Your Contact Lenses

Swimming in a pool with your contacts on or topping off your solution may seem harmless, but they could compromise your contact lenses and your vision.

Below are daily habits to adopt for optimal contact lens care:

Wash Your Hands Regularly

Whether you use daily or monthly contact lenses, make sure to first wash your hands. Placing your finger on some clear tape and seeing the mark you leave will give you some indication of what you’re putting on your contact lenses if you don’t wash and dry your hands beforehand. Avoid using scented or oily soaps, as their residue might stick to the lens surface. Similarly, avoid creams and lotions prior to inserting contacts into your eyes. 

This one simple and easy habit can make a massive difference in your eye health and can potentially prevent eye irritation and infections. 

Clean Your Contacts Daily

You must clean and disinfect your contact lenses on a daily basis, unless you use daily disposables, of course. There are several cleansing systems and solutions available — the choice depends on the type of lens you use. Speak with Dr. Karey Conway to determine the best cleaning solution for your lenses and eyes.

Avoid Contact with Water

It might seem harmless, but we advise against using tap water, as it contains impurities and microorganisms that can cause infections. Furthermore, tap water can lead your contacts to swell and change their shape. If you must swim with your contact lenses on, make sure to wear protective goggles and clean them with solution when you come out of the pool.

Never Ever Use Saliva 

Your mouth is filled with germs, which are fine for your teeth but not for your eyes. Avoid using saliva to “clean” or moisten your contact lenses.  

Do Not Top off Solution

Just as you shouldn’t mix spoiled food with fresh foods, you should not top off yesterday’s solution in your contact lens case with fresh solution. The concoction might not contain enough disinfectant to kill off organisms and clean your lenses. 

Routinely Change the Contact Lens Case

Many people don’t know about this one, but it’s recommended to change your contact lens case every 2-3 months, as microscopic dirt may linger in the case, leading to contamination and eye infections. 

Don’t Sleep with Your Lenses On

It’s important to give your cornea a chance to breathe; sleeping with your contacts may cause redness, soreness and infections. So make sure to remove your contact lenses before you get some shut-eye, unless they’re specialty lenses which are intended to be worn overnight. 

If you’re using orthokeratology (ortho-k) lenses to reshape your cornea, do wear them at night or as instructed by your eye doctor. 

Get That Annual Eye Exam

Don’t forget to book your yearly eye exam at Collierville Eye Associates in Collierville, as your vision can change. You can’t purchase new contact lenses with an expired prescription anyway, so you’ll need an updated one when your contact lens supply is running low. Furthermore, getting an exam is also an excellent opportunity to ask Dr. Karey Conway any questions you may have.

Summer Heat Wave and Your Eyes

This summer, heat waves with scorching temperatures have hit communities nationwide, making an already hot summer even hotter. With high temps and heat waves in certain areas, it’s now more important than ever to protect yourself.

For best practices and tips for maintaining healthy vision in the summer heat, talk to the Collierville Eye Associates.

How Can Heat Affect Vision?

Staying out in the sun too long can give you a sunburn and make you feel exhausted. Did you know that it can affect your vision, too?

If you get dehydrated, lack of moisture can make it hard for your eyes to naturally produce enough tears, which can contribute to seasonal dry eye. If you already have dry eye, extremely dry heat can exacerbate your symptoms of itchy, red, sore, and irritated eyes.

Do you sit in front of a fan or air conditioning system? That may feel great, but it can also contribute to dryer and less comfortable eyes.

To give your eyes some temporary relief, keep artificial tears on hand. If your eyes still feel dry or uncomfortable, contact Collierville Eye Associates.

If You Love the Sun, Read This

Golden sunshine may sound dreamy, but too much isn’t a good thing.

The sun’s ultraviolet (UV) rays can be very harmful, and your eyes are no exception. UV radiation, which can gradually contribute to eye conditions like cataracts and macular degeneration. Dr. Karey Conway recommends that you always wear sunglasses with 100% of UVA and UVB light blocking protection. There’s no shortage of trendy and sunglasses, designed with a flair for fashion, so you won’t have to compromise on style while protecting your eyes from dangerous UV rays.

Excessive sun exposure can cause headaches, blurry vision, eye pain, and eyestrain. So while you’re out at the pool, hanging out at the beach, sunbathing, or at a backyard barbeque, pay close attention to how much time you’re outside.

If you love the sunshine, you just need to protect yourself. Wear hats, sunscreen, and, of course, 100% UV protective polarized sunglasses. But if you experience discomfort or symptoms that don’t go away on their own, then it’s time to visit your eye doctor.

Computer Vision Syndrome in the Summer

There’s nothing quite like a family road trip or flying to a vacation getaway over the summer. Yet something about being stuck in the backseat of a car or inside of an airplane makes kids feel closed in and restless. It’s then that many kids will play on a smartphone, iPad, or gaming device over many hours to help pass the time.

When it comes to kids and computer use, they’re just as susceptible to the effects of digital eye strain, also called Computer Vision Syndrome, as adults are. In fact, studies show that 25% of children spend more than 3 hours each day on digital devices.

In the summer, when the heat is sizzling, it’s tempting for kids to spend more time than usual watching TV, using a computer, or playing games on their smartphones. To help ease the effects of digital eyestrain, Dr. Karey Conway suggests following the 20-20-20 rule: Every 20 minutes, take 20 seconds to look at something at least 20 feet away. It’s a great way to counteract the effects of Computer Vision Syndrome and let the eyes rest.

This summer, however you choose to beat the heat, don’t forget to protect your vision and keep your eyes strong and healthy. The Collierville Eye Associates is always here to help if you have any questions.

Have a great summer!

8 Tips to Relieve Winter Dry Eyes

Whether you live in a climate with cold winter weather or you are planning a ski trip up north, winter can be a challenge if you suffer from dry eyes. Dry, cool air, cold winds and even drier indoor heating can cause eye irritation, burning, itchiness and redness, and sometimes even excessively watery eyes as more tears are produced to compensate for the dryness. Many people have a chronic feeling that they have something in their eye and some even experience blurred vision. These symptoms can be debilitating!

Dry eyes is one of the most common complaints eye doctors get from patients during the winter season, especially in the cooler climates. That’s why we’d like to share some tips on how to relieve dry eye discomfort, and how to know when your condition is serious enough to come in for an evaluation.

Tips to Relieve Winter Dry Eyes:

  1. Keep eyes moist using artificial tears or eye drops. You can apply these a few times each day when the eyes are feeling dry or irritated. If over-the-counter drops don’t help or if you have chronic dry eyes, speak to your eye doctor about finding the best drops for you. Since not all artificial tears are the same, knowing the cause of your dry eye will help your eye doctor determine which brand is best suited for your eyes.
  2. Use a humidifier to counteract the drying effects of indoor heaters or generally dry air.
  3. Point car vents or indoor heaters away from your face when the heat is on. Try to keep your distance from direct sources of heating, especially if they blow out the heat.
  4. Drink a lot! Hydrating your body will also hydrate your eyes.
  5. Protect your eyes outdoors with sunglasses or goggles – the bigger the better! Larger, even wrap-around glasses as well as a hat with a wide brim will keep the wind and other elements out of your eyes. If you wear goggles for winter sports, make sure they fit well and cover a large surface area.
  6. Soothe dry eyes using a warm compress and never rub them! Rubbing your eyes will increase irritation and may lead to infection if the hands are not clean.
  7. Give your eyes a digital break. People blink less during screen time which is why extensive computer use can lead to dry eyes. Follow the 20/20/20 rule by taking a break every 20 minutes to look 20 feet away for 20 seconds and make sure you blink!
  8. For contact lens wearers: If you wear contact lenses, dry eyes can be particularly debilitating as the contact lenses can cause even further dryness and irritation. Contact lens rewetting drops can help your eyes feel better and may also allow you to see more clearly. Not all eyedrops are appropriate for use with contact lenses, so ask your optometrist which eyedrop is compatible with your contacts and cleaning solution. If rewetting drops don’t help, consider opting for glasses when your dry eyes are bad, and speak to your optometrist about which brands of contact lenses are better for dry eyes. Many people find dry eye improvement when they switch to daily single use contact lenses.

Chronic Dry Eyes or Dry Eye Syndrome

Dry eye syndrome is a chronic condition in which the eyes do not produce enough tear film, or do not produce the quality of tear film needed to properly keep the eyes moist. While winter weather can make this condition worse, it is often present all year round. If you find that the tips above do not alleviate your discomfort or symptoms, it may be time to see a optometrist to see if your condition requires more effective medical treatment.

Diabetes and Your Eyes

Diabetes is becoming much more prevalent around the globe. According to the International Diabetes Federation, approximately 425 million adults were living with diabetes in the year 2017 and 352 million more people were at risk of developing type 2 diabetes. By 2045 the number of people diagnosed is expected to rise to 629 million.

Diabetes is a leading cause of blindness as well as heart attacks, stroke, kidney failure, neuropathy (nerve damage) and lower limb amputation. In fact, in 2017, diabetes was implicated in 4 million deaths worldwide. Nevertheless preventing these complications from diabetes is possible with proper treatment, medication and regular medical screenings as well as improving your diet, physical activity and adopting a healthy lifestyle.

What is Diabetes?

Diabetes is a chronic disease in which the hormone insulin is either underproduced or ineffective in its ability to regulate blood sugar. Uncontrolled diabetes leads to hyperglycemia, or high blood sugar, which damages many systems in the body such as the blood vessels and the nervous system.

How Does Diabetes Affect The Eyes?

Diabetic eye disease is a group of conditions which are caused, or worsened, by diabetes; including: diabetic retinopathy, diabetic macular edema, glaucoma and cataracts. Diabetes increases the risk of cataracts by four times, and can increase dryness and reduce cornea sensation.

In diabetic retinopathy, over time, the tiny blood vessels within the eyes become damaged, causing leakage, poor oxygen circulation, then scarring of the sensitive tissue within the retina, which can result in further cell damage and scarring.

The longer you have diabetes, and the longer your blood sugar levels remain uncontrolled, the higher the chances of developing diabetic eye disease. Unlike many other vision-threatening conditions which are more prevalent in older individuals, diabetic eye disease is one of the main causes of vision loss in the younger, working-age population. Unfortunately, these eye conditions can lead to blindness if not caught early and treated. In fact, 2.6% of blindness worldwide is due to diabetes.

Diabetic Retinopathy

As mentioned above, diabetes can result in cumulative damage to the blood vessels in the retina, the light-sensitive tissue located at the back of the eye. This is called diabetic retinopathy.

The retina is responsible for converting the light it receives into visual signals to the optic nerve in the brain. High blood sugar levels can cause the blood vessels in the retina to leak or hemorrhage, causing bleeding and distorting vision. In advanced stages, new blood vessels may begin to grow on the retinal surface causing scarring and further damaging cells in the retina. Diabetic retinopathy can eventually lead to blindness.

Signs and Symptoms of Diabetic Retinopathy

The early stages of diabetic retinopathy often have no symptoms, which is why it’s vitally important to have frequent diabetic eye exams. As it progresses you may start to notice the following symptoms:

  • Blurred or fluctuating vision or vision loss
  • Floaters (dark spots or strings that appear to float in your visual field)
  • Blind spots
  • Color vision loss

There is no pain associated with diabetic retinopathy to signal any issues. If not controlled, as retinopathy continues it can cause retinal detachment and macular edema, two other serious conditions that threaten vision. Again, there are often NO signs or symptoms until more advanced stages.

A person with diabetes can do their part to control their blood sugar level. Following the physician’s medication plan, as well as diet and exercise recommendations can help slow the progression of diabetic retinopathy.

Retinal Detachment

Scar tissues caused by the breaking and forming of blood vessels in advanced retinopathy can lead to a retinal detachment in which the retina pulls away from the underlying tissue. This condition is a medical emergency and must be treated immediately as it can lead to permanent vision loss. Signs of a retinal detachment include a sudden onset of floaters or flashes in the vision.

Diabetic Macular Edema (DME)

Diabetic macular edema occurs when the macula, a part of the retina responsible for clear central vision, becomes full of fluid (edema). It is a complication of diabetic retinopathy that occurs in about half of patients, and causes vision loss.

Treatment for Diabetic Retinopathy and Diabetic Macular Edema

While vision loss from diabetic retinopathy and DME often can’t be restored, with early detection there are some preventative treatments available. Proliferative diabetic retinopathy (when the blood vessels begin to grow abnormally) can be treated by laser surgery, injections or a procedure called vitrectomy in which the vitreous gel in the center of the eye is removed and replaced. This will treat bleeding caused by ruptured blood vessels. DME can be treated with injection therapy, laser surgery or corticosteroids.

Prevent Vision Loss from Diabetes

The best way to prevent vision loss from diabetic eye disease is early detection and treatment. Since there may be no symptoms in the early stages, regular diabetic eye exams are critical for early diagnosis. In fact diabetics are now sometimes monitored by their health insurance to see if they are getting regular eye exams and premium rates can be affected by how regularly the patients get their eyes checked. Keeping diabetes under control through exercise, diet, medication and regular screenings will help to reduce the chances of vision loss and blindness from diabetes.

Inside a Life With Color Vision Deficiency

What’s it like to be color blind? Contrary to what the name implies, color blindness usually does not actually mean that you don’t see any color, but rather that you have difficulty perceiving or distinguishing between certain colors. This is why many prefer the term color vision deficiency or CVD to describe the condition. CVD affects men more than women, appearing in approximately 8% of men (1 in 12) and .5% of women (1 in 200) worldwide. 

Having color vision deficiency means that you perceive color in a more limited way than those with normal color vision. This ranges from mild, in which you may not even be aware that you are experiencing color differently, to severe, which is perhaps the more appropriate from to be called “color blind” and involves the inability to see certain colors. 

CVD can be inherited; it is caused by abnormalities in the genes that produce photopigments located in the cone cells in your eyes. The eyes contain different cone cells that fire in response to a specific color, blue, green or red and together allow you to see the depth and range of colors that the normal eye can see. The type of color blindness and therefore the type of color vision that is impaired, is based on which photopigments are abnormal. The most common form of CVD is red-green, followed by blue-yellow. Total color blindness or the complete inability to perceive color is quite rare. About 7% of males have congenital color blindness that they inherit from the mother’s X-chromosome. 

Color blindness can also be the result of eye damage, specifically to the optic nerve, or to the area in the brain that processes color. Sometimes an eye disease, such as cataracts, can also impact one’s ability to perceive color. Systemic diseases such as diabetes or multiple sclerosis can also cause acquired CVD. 

Living with CVD

Red-green color blindness does not mean only that you can’t tell the difference between red and green, but rather that any color that has some red or green (such as purple, orange, brown, pink, some shades of gray, etc) in it is affected. 

You many not realize all of the ways you use even subtle distinctions in color in your daily life. Here are some examples of ways that CVD can impact your life and make seemingly everyday tasks challenging:

  • You may not be able to cook meat to the desired temperature based on color. 
  • Most of the colors in a box of crayons will be indistinguishable.
  • You may not be able to distinguish between red and green LED displays on electronic devices that indicate power on and off. 
  • You may not be able to tell between a ripe and unripe fruit or vegetable such as bananas (green vs. yellow) or tomatoes (red vs green). 
  • Chocolate sauce, barbecue sauce and ketchup may all look the same. 
  • Bright green vegetables can look unappealing as they appear greenish, brown or grey. 
  • You may not be able to distinguish color coded pie charts or graphs (which can cause difficulty in school or work). 
  • Selecting an outfit that matches can be difficult. 

Knowing that one is color blind is important for some occupations that require good color discrimination such as the police officers, railway workers, pilots, electricians etc.  These are just a few of the ways that CVD can impact one’s daily life. So is there a cure? Not yet. 

While there is no cure for CVD, there is research being done into gene therapies and in the meantime there are corrective devices available including color vision glasses (such as the Enchroma brand) and color filtering contacts that for some can help to enhance color for some people. If you think you might have CVD, your optometrist can perform some tests to diagnose it or rule it out. If you have CVD, you can speak to your eye doctor about options that might be able to help you experience your world in full color. 

Pink, Stinging Eyes?

Conjunctivitis, also called pink eye, is one of the most frequently seen eye diseases, especially in kids. It can be caused by viruses, bacteria or even allergies to pollen, chlorine in swimming pools, and ingredients in cosmetics, or other irritants, which touch the eyes. Some forms of conjunctivitis might be quite transmittable and quickly spread in school and at the office.

Conjunctivitis is seen when the conjunctiva, or thin transparent layer of tissue covering the white part of the eye, becomes inflamed. You can identify conjunctivitis if you notice eye redness, discharge, itching or swollen eyelids and a crusty discharge surrounding the eyes early in the day. Pink eye infections can be divided into three main types: viral, allergic and bacterial conjunctivitis.

The viral type is usually a result of a similar virus to that which produces the recognizable red, watery eyes, sore throat and runny nose of the common cold. The red, itchy, watery eyes caused by viral pink eye are likely to last from a week to two and then will clear up on their own. You may however, be able to reduce some of the discomfort by using soothing drops or compresses. Viral pink eye is transmittable until it is completely cleared up, so in the meantime maintain excellent hygiene, remove eye discharge and try to avoid using communal pillowcases or towels. If your son or daughter has viral conjunctivitis, he or she will have to be kept home from school for three days to a week until symptoms disappear.

A bacterial infection such as Staphylococcus or Streptococcus is usually treated with antibiotic eye drops or cream. One should notice an improvement within just a few days of antibiotic drops, but be sure to adhere to the full prescription dosage to prevent pink eye from recurring.

Allergic pink eye is not contagious. It is usually a result of a known allergy such as hay fever or pet allergies that sets off an allergic reaction in their eyes. First of all, to treat allergic pink eye, you should eliminate the irritant. Use cool compresses and artificial tears to relieve discomfort in mild cases. When the infection is more severe, your eye doctor might prescribe a medication such as an anti-inflammatory or antihistamine. In cases of chronic allergic pink eye, topical steroid eye drops could be used.

Pink eye should always be diagnosed by a qualified eye doctor in order to identify the type and best course of treatment. Never treat yourself! Keep in mind the sooner you begin treatment, the lower chance you have of giving pink eye to loved ones or prolonging your discomfort.

How to Safely View the Great American Eclipse of 2017

On August 21st, for the first time since 1979, a solar eclipse will be visible across North America. What’s even more historic is that it will also be the first time an eclipse will be visible across the continent, from coast to coast, since 1918. If you want to bear witness to this historic event, it is important to do so safely which means being knowledgeable about the event and prepared to protect your eyes from potential serious damage and vision loss.

First of all, here are the facts about the upcoming eclipse. A total solar eclipse is when the moon completely blocks the face of the sun (called the photosphere) leaving only the sun’s outer ring, called the corona, in view. This event happens briefly, and will only be visible for certain parts of the United States for up to two minutes and forty seconds during the upcoming celestial event. All of North America, including mainland US and Canada, however, will be able to view a partial eclipse for the duration of about two to three hours. You can search online to see which part of the eclipse will be visible from your location and what time you will be able to see it.

With 500 million people in the viewing range of the eclipse, thousands are excitedly preparing for what could be for many a once-in-a-lifetime experience, however, it’s crucial to make sure that this is done safely to protect your eyes and vision from serious damage that can occur from viewing an eclipse without proper eye protection.

Looking at a Solar Eclipse

Viewing a solar eclipse without proper eye protection is extremely dangerous and can cause permanent vision loss. Looking directly at the sun can cause a condition called Solar Retinopathy or retinal burns which can cause damage to and destroy cells in the retina, which communicates visual cues with the brain. It can also burn the macula which is responsible for central vision. While we usually have a hard time looking directly at the sun which helps to protect us from this condition, during an eclipse because the sun is partially covered by the moon, looking directly at the sun becomes less difficult. Nevertheless, the exposure to the damaging rays of the sun is just as strong and therefore the risk just as great.

It’s important to note that solar burns to the retina do not cause symptoms during that time that you are looking at the eclipse. There is no pain or discomfort. However, the longer you look at it, the deeper the hole that burns through the retina and you would not notice the vision loss until hours later. There is no treatment for solar retinopathy. Many will notice recovery in vision, but depending on the severity of damage there may be only partial recovery which may take up to 6 months after viewing the eclipse.

Eclipse Glasses: Solar Eclipse Eye Protection

Do not view the eclipse without proper eye protection. Protecting your eyes during an eclipse with specially designed eyewear or solar viewers is a must. The American Optometric Association and NASA have released the following statement regarding eye protection: “There is only one safe way to look directly at the sun, whether during an eclipse or not: through special-purpose solar filters. These solar filters are used in “eclipse glasses” or in hand-held solar viewers. They must meet a very specific worldwide standard known as ISO 12312-2.”

It’s important to note that regular sunglasses are not sufficient in protecting your eyes. Here are some additional safety tips issued by NASA for viewing the eclipse:

  • Stand still and cover the eyes with eclipse glasses or solar viewer before looking up at the bright sun. After glancing at the sun, turn away and remove the filter—do not remove it while looking at the sun.
  • Do not look at the un-eclipsed or partially eclipsed sun through an unfiltered camera, telescope, binoculars or other optical device. Similarly, do not look at the sun through a camera, a telescope, binoculars, or any other optical device while using your eclipse glasses or hand-held solar viewer—the concentrated solar rays will damage the filter and enter your eye(s), causing serious injury.
  • If you are within the path of totality, remove your solar filter only when the moon completely covers the sun’s bright face and it gets quite dark.

If you plan to view the eclipse, make sure that you plan ahead and obtain eclipse glasses or solar viewers for every person that plans to enjoy the experience. Keep this once in a lifetime experience a safe and enjoyable one.

To obtain eclipse glasses, contact your local optometrist, or visit the American Optometry Association website for more information.

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

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 about the best options for your condition.
