Successful Contact Lens Wear

Proper contact lens care is essential for the best contact lens wearing experience

contact lens and eye

Contact lens wear is quite safe as long as proper lens and storage case care are followed. Improper lens wear and care can put the lens wearer at risk for serious consequences. Sight-threatening microbial keratitis (corneal ulcer) is the most significant adverse event associated with contact lens wear and is largely preventable.
Single-use or daily disposable soft lenses are prescribed to be worn once and discarded. This is the safest soft lens wearing modality because no lens cleaning, lens care or storage case is required.
The contact lens storage case is the most likely potential reservoir for contact lens related ocular infections. Contact lens cases are not meant to be family heirlooms. Replace the case at least every 3 months.

General Contact Lens Care Instructions

  • Hand washing: always wash your hands before handling contact lenses. Use mild, basic soap and avoid  deodorant, scented or moisturizing liquid soaps.
  • Cleaning, rinsing and disinfection: Digital cleaning (rubbing the lens with your finger on your palm) removes dirt and debris and prepares the lens surfaces for disinfection. Rub and rinse thoroughly, even if the product is labeled “no rub.” Lens storage solutions contain chemicals that inhibit or kill potentially dangerous microorganisms while the lenses are soaked overnight.
  • Do not re-use old solution or “top-off” the liquid in the lens storage case. Empty the storage case daily and always use fresh solution.
  • Do not use lens care products beyond their expiration dates. Discard opened bottles after 30 days.
  • Do not allow the tip of the solution bottle to cone in contact with any surface, and keep the bottle tightly closed when not in use.
  • Make-up Removal: Insert contact lenses before applying contact lenses. Take contact lenses off before thoroughly removing make-up every night.
  • Keep contact lens storage case clean, inside and out. Replace the case at least every 3 months.

What’s the Vitreous?

The vitreous is a gel like substance that fills most of the eye. It is critical during the development of the eye.  After the eye is developed the vitreous simply fills space inside of the eye. flashes and floaters
The vitreous is often the cause of many problems in the eye. If the vitreous tugs on the retina and it can cause a retinal tear. This happens when the vitreous detaches (Posterior Vitreous Detachment) or when the eye is injured.
Epiretinal membrane or cellophane maculopathy are microscopic types of vitreous traction on the macula. An epiretinal membrane can distort the vision.
Floaters are the most common annoyance caused by the vitreous. For some people floaters impair the vision by causing spots or blur.
For severe retinal/vitreal complications the vitreous is removed (vitrectomy). Removing the vitreous is not without risk and is often performed as part of other retinal procedures.

Benefits of Ultraviolet Light

Usually I am preaching the dangers of Ultraviolet (UV) exposure, and I will do a bit of that, but there are some benefits to sunshine. Sun and the Eyes
Vitamin D – Vitamin D is a fat soluble vitamin that is naturally present in very few foods. It is produced endogenously when ultraviolet rays from the sun strike the skin and trigger vitamin D synthesis. It is  essential for maintaining bone health. Vitamin D promotes the absorption of calcium in the gut to enable normal bone growth and maintenance. It may also protect against the development of cancer, autoimmunity, rheumatoid arthritis, hypertension, multiple sclerosis, type I and II diabetes and infectious disease. Although vitamin D can be obtained through vitamin supplementation, most people in the world derive their vitamin D from sun exposure.
Low vitamin D levels may increase the chance of developing age-related macular degeneration (AMD), a minimum exposure to UV light may be necessary for the production of vitamin D. (this does not mean it is OK to stare at the sun). UV exposure should be moderate; too much and the risk for AMD increases, as does the risk with too little UV.
PterygiumThere are acute effects on the eyes from too much sun exposure such as photokeratitis (a sunburn on the surface of the eye). Long-term UV exposure can cause cataracts and pterygium (a growth on the white of the eye). Wearing sunglasses when outdoors is a simple way to prevent over-exposure of UV light to the eyes.

The amount of protection from sunglasses varies depending on the material of the lens and added coatings. For maximum protection look for lenses that block 90% of UVA and 99% of UVB.
Currently, the UV index can be used as a rough guide for knowing when the skin and eyes need protection. Sunscreens with a sun protection factor (SPF) of 8 or more appear to block vitamin D producing UV rays. Because we typically do not apply sufficient amounts of sunscreen or cover all exposed skin, synthesis of vitamin D probably occurs. The maximum amount of exposure needed to maintain normal vitamin D levels is 30 minutes twice a week. For some people 5 minutes twice a week is adequate. Again moderation, more is not better.

 

 

Rosacea Awareness Month

Rosacea affects the eyes in many patients, and may result in a watery or bloodshot appearance, irritation and burning or stinging. The eyelids may also become swollen, and styes are common.

April has been designated as Rosacea Awareness Month with the intent to educate the public on the warning signs of this chronic but treatable facial disorder. Rosacea is a common but poorly understood disorder of the facial skin that is estimated to affect well over 16 million Americans — and most of them don’t know it. In fact, while rosacea is becoming increasingly widespread as the populous baby boom generation enters the most susceptible ages, a National Rosacea Society survey found that 95 percent of rosacea patients had known little or nothing about its signs and symptoms prior to their diagnosis.

Rosacea typically presents anytime after the age of 30 and may initially resemble a simple sunburn or an inexplicable blush. Suddenly, without warning, a flush comes to the cheeks, nose, chin or forehead. This recurs over and over with the redness lasting longer each time and eventually visible blood vessels may appear. Without treatment, bumps and pimples often develop, growing more extensive over time and burning and itching are common.

In severe cases, especially in men, the nose may become enlarged from the development of excess tissue. This is the condition that gave comedian W.C. Fields his trademark red, bulbous nose. The eyes can be affected too. Ocular involvement includes watery, burning and bloodshot eyes.

Ongoing research has suggested that rosacea may be caused by various possible factors, including defects of the immune system, nervous system, facial blood vessels and genetics. Most recently the presence of microbes and Demodex mites on the skin can trigger symptoms. Demodex are normal inhabitants of human skin but occur in far greater numbers in people with rosacea. It is believed that an immune response to bacteria associated with the mites may lead to the inflammatory bumps and pimples.

A study by a dermatologist at Duke University found a significant association between the relative presence of the mites and the development of rosacea, suggestion that the microscopic mites may be involved in the disease process. The study authors also proposed that increased mite density in the skin might trigger inflammatory response, block hair follicles or help transmit other bacteria in the skin , leading to signs and symptoms of rosacea.

Demodex mites also live in the eyelash follicles. they survive on dead skin and protein. We have found that reducing the number of Demodex living on the eyelid can reduce dry eye symptoms of burning and waterness. Controlling the Demodex requires a special cleaning solution containing a derivative of Tee Tree Oil. If you have or suspect you have rosacea and are suffering from burning red eyes, make an appointment in our dry eye clinic for evaluation and treatment.

Although the definitive cause of rosacea remains unknown, a vast array of lifestyle and environmental factors have been found to trigger flare-ups of signs and symptoms in various individuals. Common rosacea triggers include sun exposure, emotional stress, hot or cold weather, wind, heavy exercise, alcohol, spicy foods, heated beverages, humidity, certain skin-care products and potentially an overabundance of Demodex mites.

Signs and Symptoms of Rosacea

  • Redness on the cheeks, nose , chin or forehead
  • Small visible blood vessels on the face
  • Bumps or pimples on the face
  • Watery or irritated eyes

Omega-3 Eye Benefits

Omega-3 is an essential fatty acid (EFA). EFAs are important nutrients critical for the normal production and functioning of cells, muscles, nerves and organs. Fatty acids also are required for the production of hormone-like compounds that help regulate blood pressure, heart rate and blood clotting.

Several studies suggest that omega-3 fatty acids may help protect adult eyes from macular degeneration and dry eye disease. In a large European study , participants who ate oily fish like salmon at least once a week had half the risk of developing wet macular degeneration, compared with those who ate fish less than once a week.

In India a study was done with computer users. Half of the group were given 2 capsules of omega-3 fatty acids and the other group was given 2 capsules of a placebo. Each group took the supplements for 3 months. At the end of the 3 month trial a survey of the participants revealed dry eye symptoms diminished after dietary intervention with the omega-3 supplements . The omega 3 users also reduced abnormal tear evaporation and increased the density of the conjunctival goblet cells on the surface of the eye. The goblet cells secrete substances that lubricate the eye during blinks, stabilize the tear film and reduce dryness.

The typical American diet, characterized by significant amounts of meat and processed foods, tends to contain 10 to 30 times more omega-6 than omega-3 fatty acids. This imbalance of  fatty acids appears to be a contributing cause of a number of serious health problems, including heart disease, cancer, asthma, arthritis and depression.

One of the best steps you can take to improve your diet is to eat more foods that are rich in omega-3 fatty acids and fewer that are high in omega-6 fatty acids.

The best food sources of a beneficial omega-3 FA are cold-water fish. The American Heart Association recommends a minimum of two servings of cold water fish weekly to reduce the risk of cardiovascular disease, and many eye doctors likewise recommend a diet high in omega-3 fatty acids and/or supplements to reduce the risk of eye problems.

If you don’t care for the taste of fish, another way to make sure your diet contains enough omega-3 is to take fish oil supplements. These are available in capsule and liquid form and many varieties feature a “non-fishy” taste. The best time to take the supplement is with a meal so it is absorbed better.

Other good sources of omega-3 include flaxseed, flaxseed oil, walnuts and dark leafy vegetables. However, your body can’t process the vegetarian sources as easily as the fatty acid found in fish.

Too much Omega-6 can interfere with the body’s absorption of omega-3. To reduce your intake of omega-6s, avoid fried and highly process foods. Many cooking oils including sunflower oil and corn oil are very high in omega-6 fatty acids. High cooking temperatures also create harmful trans-fats.

Trans fats may contribute to a number of serious diseases, including cancer, heart disease, atherosclerosis, high blood pressure, diabetes, obesity, arthritis and immune system disorders.

For a more nutritious diet and potentially better eye health try theses simple changes:

  1. Replace cooking oils that are high in omega-6 fatty acids with olive oil, which has significantly lower levels of omega-6 fatty acids.
  2. Eat plenty of fish, fruits and vegetables.
  3. Avoid hydrogenated oils (found in many snack foods) and margarine.
  4. Avoid fried foods and foods containing trans fats.
  5. Limit your consumption of red meat.

Book Review – Thinking in Pictures

grandin

I picked this book up for no particular reason, I wasn’t even sure what to expect. I’m intrigued by Temple Grandin the author of Thinking in Pictures – My Life with Autism. I was first introduced to her life in a movie, Temple Grandin. She is an expert on animal behavior and is responsible for designing many of the humane livestock-handling facilities in the US. She is also a spokeswoman for autism.

The book begins with Grandin describing her life with autism. She describes her difficulties learning as a child with autism. She developed a strategy of utilizing her extraordinary visual spatial skills to create a “video library.” Her verbal skills were very poor, but Temple’s brain processed everything as a picture. The video library is a resource for her in deciding how to behave in a social situation and allows her to design equipment and systems to move animals. Instead of drawing or verbally describing an idea, Grandin visualizes the design in every possible situation, with different breeds of cattle and in different weather conditions. She can predict flaws prior to construction. Her brain works like a virtual reality computer system only her perception is much more enhanced.

A significant portion of the book is dedicated to autism. I found this very interesting as my own knowledge of the condition is very limited. She impresses the fact that there is a “spectrum.” From low functioning to asperger’s, and each autistic individual has unique capabilities.

Grandin offers many suggestions and resources for parents of an autistic child. Many of the suggestions would benefit a parent of any child.For example, she discouraged the use of video games because the child becomes so addicted that he has no other interests. She doesn’t advocate a complete ban as it does give the child something to talk to other children about. General recommendations include social skills and manners. Temple was required to sit through formal Sunday dinners and behave. (sometimes she did). Rudeness was not tolerated and “please” and “thank you” were required. Again, these are social skills all children should learn. Playing games provided a situation to learn turn-taking, sharing and patience.

Oversensitivity is common for most autistics. Any of the senses can be a trigger – scratchy clothes, loud noises and bright lights can cause distress for an autistic person. I always think of the squeeze chute when I think of Temple Grandin. A squeeze chute is used to confine and calm cattle for branding, vaccines and tagging. Temple found personal comfort in a squeeze chute she build for herself. Occupational therapists create treatments to calm the nervous system, it can be swinging, a weighted vest or body massage. All intended to desensitize the nervous system.

I feel obliged to talk a little about her pages on the visual sense. I haven’t seen any unusual eye conditions that are more common in autistics, but the oversensitivity can be a problem. Avoiding bright lights and flickering lights with filters or using incandescent instead of fluorescent bulbs are solutions. For any child with visual processing problems a developmental optometrist can create a program of exercises to help the eyes and brain to work together.

Like anything having to do with the nervous system, early intervention is critical. The nerves and brain are still plastic and developing in young children. It is important to start therapy and education when an autistic child is young, so that developing nerve endings can make the right connections.

There is a whole chapter on medications. Like the variations in autism, so are the drugs, dosage and results. Temple encourages individuals and/or parents to closely monitor the use of pharmaceutical and amounts. Apparently, responses are vastly different for people with autism.

The book ends with Grandin’s search for the elusive answer to “what happens when we die?”  As she spends so much time in cattle yards and slaughterhouses, she is not inexperienced on death so naturally she thinks about what’s next? She has a dream that takes place in a slaughterhouse, but she describes the upper floors. And as is typical of dreams the location doesn’t really make sense. What she finds in the upper levels consists of, “beautiful museums and libraries that contained much of the world’s culture. As I walked through the vast corridors of knowledge, I realized that life is like the library and the books can be read only one at a time, and each one will reveal something new.”

After reading Thinking in Pictures I have revealed many new things to myself, not just on autism, but people.

 

 

Presbyopia

in need for glasses

Have you ever been in a restaurant trying to decide what to order? The lights are dim, you are practically burning up the menu manipulating it around the candle for more light… Or how about trying to hook up wires behind the TV or computer, can’t find the right hook-up? The above situations make presbyopia seem like an acute condition. Things that looked OK at the kitchen table by the window don’t seem as clear in the dark or when you are tired.

Presbyopia is the result of an aging process on the lens of the eye. The lens focuses light at all distances without much effort for the first forty plus years of our lives. Then kablamo…you can’t see to remove a sliver from your child’s finger.

Denial is the most common response. Eventually, presbyopia interferes with work. You find yourself switching numbers or getting headaches at the computer. Your over-all efficiency is diminished and your frustration is elevated. Sometimes a pair of reading glasses will solve the problem. Depending on your prescription and how you use your eyes, multifocals offer clear vision at multiple distances. Contact lens wearers can try monovision (an adjustment in the correction of one lens) or bifocal contact lenses.

Just know that you are not in this alone, my presbyopic eyes and I are here ready to help you. Stop struggling and let’s find a solution.
