Many people in the twin cities do not leave home without their sunglasses; yet, others may not recall the last time they used a pair of sunglasses. Designer sunglasses are sometimes used as fashion accessory, but more importantly, sunglasses should be used to protect your eyes and the skin around the eyes from harmful UV rays. You may be aware of the principal danger posed by the sun when it comes to skin cancer; however, are you aware of the potential ocular damage that can be caused by ultraviolet radiation?



The effects of UV rays are cumulative and can lead to eye problems later in life. The most common eye problems that we see from exposure to the sun include: Cataracts, Macular Degeneration, Pinguecula, Pteygium and Skin Cancer around the eyelids. Overexposure to UV radiation can also lead to inflammation of the cornea and the conjunctiva. Inflammation of cornea due to sun exposure is known as Photokeratitis and can prove to be rather painful. It is worth noting that Photokeratitis can also be caused by tanning beds and welder's flash.

According to the American Optometric Association, Cataracts and Age Related Macular Degeneration are two of the leading causes of reduced vision in the United States. Gradual development of cataracts is a normal part of the aging process; however, there are a number of factors that can speed up the aging process and not wearing sunglasses is one that can easily be helped. Cataracts can be removed by surgery but currently, there is no cure for Macular Degeneration. Research indicates that green leafy vegetables and certain vitamin supplements may help slow the progression of macular degeneration. Ask your physician or eye care provider about these vitamins before starting any new supplements. Like UV radiation, smoking is also linked to the development of macular degeneration. To complicate the matter, if a smoker or recent ex-smoker starts consuming vitamin A supplements, that person could potentially increase his or her chances of developing lung cancer. It is always wise to discuss your full medical history with your eye doctor during your comprehensive eye examinations.

So, what can an individual do to reduce their chances of developing the above mentioned ocular problems? The best recommendation would be to wear sunglasses with 100% UV protection when you are involved in outdoor activities. In addition to wearing sunglasses, consider wearing a hat while in the sun and see your optometrist for annual comprehensive eye exams to maintain your eye health. Don't forget eye protection for children & teenagers as they typically spend more time in the sun than adults.
