“Enhancing vision today…to help reach goals for tomorrow” is more than a motto. It is the essence of our practice.—Dr. Wylie

The Sixties.............War, peace, expressing yourself, the Civil Rights movement, and the Beatles. One of the biggest hits of the era was “Here Comes the Sun” by the Beatles. 

In the health care world, the sun plays a balancing role in delivering its rays to our bodies to help produce Vitamin D. Many people who work indoors are directed to take Vitamin D supplements because of lack of exposure to the sunshine, Conversely, people who are outside a lot have a risk of overexposure causing skin cancer.

The eyes are at risk as well. If sunglasses are not worn, there is a greater risk for cataracts or skin cancers of the eyelids. It is important to know that not all sunglasses are made alike. UV A, B, and C rays are the harmful rays that sunglasses need to protect us from.

However, many over the counter sunglasses do not have UV protection built into the lenses, which can actually cause more damage especially in children. 80% of sun exposure in our lives comes in childhood. Without UV protection in sunglasses, the pupil which dilates more behind a sun lens, allows more of the harmful rays of the sun in.

The whole point is for the consumer to be aware that it is vital to buy sunwear that has UV protection built into the lenses. Polarized lenses protect the eyes from the sun as well as from glare from the road and water.

Fisherman love polarized lenses because you can see the fish right through the water. People who boat also claim their vision is better because glare off the water is reduced.

So next time you hear the famous Beatles hit, remember to be educated on the best products for your eyes, to keep you healthy and prevent cataracts and cancer. Remember, UV protection in sunglasses is the way to go.

You wouldn’t dream of going to the beach without sunscreen on, or snow skiing without goggles to protect you from ”snow blindness”..... So what do you do to protect your eyes from potentially harmful blue light from screens? Blue light exposure is at an all time high, with the average viewer spending greater than 5 hours per day behind some sort of screen device.

New research is exploring the effect of light rays emitted from phones, computers, television, and some LCD lights to see the effect on the retina and lens of the eye. The blue light spectrum is a portion of the visible light spectrum similar to UV-A and UV-B. UV-B exposure has been a known cause of cortical cataracts. This is leading researchers to conclude that this exposure needs to be studied more.

“New research evidence suggests that high energy visible light from artificial sources may not be entirely harmless,” from Karl Citek, O.D.,Ph.D., Chairman of the American Optometric Association Commission on Ophthalmic Standards. With this in mind, more research globally on this portion of the light spectrum has now ensued.

One of the potential effects are the increased risk of macular degeneration because the delicate macular cells of the retina can be affected by long term exposure to certain wavelengths. Another event being studied is the effect on sleep habits.

You see, blue light exposure right before bedtime may inhibit sleep because the blue light keeps us alert, and blocks the production of melatonin which puts us to sleep. So stopping use of your computer one hour before bedtime is recommended in order for the body to properly produce the melatonin you need to fall asleep easily.

Treatments for limiting exposure to harmful blue rays comes in the form of tinted lenses. Yellow, amber, orange or red lenses can protect more fully from any potential hazards of blue light exposure. There are also anti-reflective lens treatments that are quite effective put out by major lens companies.

Overall, more research is definitely needed, but there may be a moment in the future that putting on “screen time “ glasses will be as common as sunscreen.

Do you have the right kind of eyewear to protect yourself from serious injury or blindness - or even just daily irritation?

Ask us about blue light protectionEach year, tens of thousands of people are treated for eye injuries related to the hazards of their jobs, doing chores in the yard or playing sports. Most of these injuries could have been prevented by the right kind of eye protection - including wearing safety glasses, goggles or safety shields.

And for those not exposed to physical dangers, there are coatings that can be added to your regular glasses that protect you from UV rays from the sun and blue light from computer screens.

Ask us about how the right eye protection can help save your sight and what options you have based on your individual needs.

The effects of mobile computing on health

Our world has been inundated with mobile devices – smartphones, tablets, laptops and portable gaming systems are used daily. The proliferation of these electronic devices has been interwoven into the fabric of our society, transforming our culture into an always connected global community.

Smartphones, computer screens, tablets and most other back-lit devices emit High Energy Visible Light (HEVL) radiation and while these connected devices have made our lives easier, the daily use of these digital experiences may cause health risks.

Healthy human beings are born with natural defenses to this type of light. However, the aging process can deteriorate our ability to adequately deal with excessive or accumulated exposure.

What are the strategies to protect against the modern bombardment of blue light?

The easy answer would be to forsake all modern conveniences and return to a simpler way of life free from the electronic trappings of the 21st century, but for those not willing to part with their beloved devices, try HOYA’s solution, the new lens treatment Recharge.

This ophthalmic lens treatment provides a measure of health protection against the harmful effects of blue light. It also provides improved contrast and visual comfort when viewing digital back-lit devices. In addition to these benefits, Recharge reduces glare and reflections and provides superior scratch resistance.

The most effective way to reduce blue light exposure is to limit the daily use of digital devices. However, Recharge can help to reduce long-term accumulation of HEVL and the health risks associated with this new digital age, especially when complemented by special lens designs like Hoyalux TACT, ideal for office and computer work or Nulux Active 8 for active lifestyles in a media driven world.

Dry Eye Syndrome is characterized by itching, burning, gritty, red eyes. There are many causes for Dry Eye and, consequently there are many treatments.

Your tears serve many important functions. They wash out debris, keep your eyes moist and have special enzymes that neutralize microorganisms that colonize your eyes. Tears are made up of three layers, the lipid, aqueous and mucus layers. The lipid layer is the outer oily section, the aqueous layer is the watery middle part, and the mucus layer is the inner section closest to your cornea. The layers are produced by different glands in your eyelid and a problem with any of them can cause dry eye syndrome. If left untreated, dry eye can cause tissue damage and scarring of the cornea, leading to major vision problems.

There are many factors that can cause dry eyes. Age, certain medications, insufficient blinking, chemical composition of tears and environmental factors like sunlight, wind, dust and smoke. Dry Eye is also the number one complaint of people who wear contact lenses. With all of these potential causes there are also a variety of ways to treat dry eyes.

Artificial tears drops can help simulate tears in your eyes, reducing redness and clearing vision. Wearing sunglasses, cleaning furnace and air conditioning filters, avoiding smoke and using a humidifier can also help you reduce dryness. If you are having problems with a medication or if you wear contact lenses and are experiencing dry eyes, consult with your eye care provider to explore other options.

Because of the wide array of causes and solutions for dry eye, make sure to visit with your eye care provider to determine the best solution for you.

Obesity is now hitting critical levels, and affecting every branch of medicine. The Center of Disease control (CDC) now reports obesity affects 4 out of 10 people. Furthermore, 3 out of 10 people are considered overweight, just shy of obese. The effect on eyes is greatest on the small blood vessels of the eye, which can cause bleeding which leads to blindness. This is mostly in association with systemic diabetes or hypertension in which obesity is a leading factor. Obesity has a very real and lasting effect on individuals and families.

Certain health effects that come as result of obesity are as follows:

Cancer: In some cases, excess fat cells can affect the growth of tumors, according tho the NCI (National Cancer Institute), and thousands of cancer cases are linked directly to obesity.

High blood pressure: Aneurism,stroke, heart failure, and death are the consequences of hypertension. According to the American Heart Institute, obesity is a leading cause of heart disease. Blood pressure is simply the force of the blood pushing against the arteries, and too much pressure weakens those vessels over time. Obesity causes these vessels to strain more than normal.

Diabetes (type 2): Being obese puts extra work and stress on the body’s natural ability to maintain proper glucose levels for the bloodstream, which in turn creates a greater need for insulin. Over time, the body cannot make enough insulin to keep up, thus creating a diabetic state. Over 80% of people with type 2 diabetes are overweight, so decreasing obesity can markedly lower your chance of developing type 2 diabetes.

Infertility and premature birth: Overweight women have greater risk in delivery, because too much fat can weaken the cervical membranes. Additionally,overweight women have more trouble getting pregnant because of the effect of obesity on hormonal changes that impact conception.

Insomnia: According to the American Sleep Foundation, obesity is linked to sleep apnea, preventing a restful night sleep. Interruption in sleep patterns due to momentary gasping for breath can have a poor overall effect on all health aspects of life.

Losing weight through daily diet, exercise, and the help of your physician and dietician are viable solutions and treatment for obesity. Eliminating obesity can attribute to a healthier lifestyle and in many cases can extend or save your vision and your life.
