When soft contact lenses first came on the scene, the ocular community went wild. People no longer had to put up with the initial discomfort of hard lenses, and a more frequent replacement schedule surely meant better overall health for the eye, right? In many cases this was so. The first soft lenses were made of a material called HEMA, a plastic-like polymer that made the lenses very soft and comfortable. The downside to this material was that it didn’t allow very much oxygen to the cornea (significantly less than the hard lenses), which bred a different line of health risks to the eye. As contact lens companies tried to deal with these new issues, they started to create frequent-replacement lenses that made from SiHy, or silicone hydrogel. The oxygen transmission problem was solved, but an interesting new phenomenon occurred. Because these were supposed to be the “healthiest” lenses ever created, many people started to over wear their lenses, which led to inflamed, red, itchy eyes; corneal ulcers; and hypoxia (lack of oxygen) from sleeping in lenses at night. A new solution was needed. Thus was born the daily disposable contact lens, which is now the go-to lens recommendation of most eye care practitioners. Daily disposables (dailies) are for one-time use, and therefore there is negligible risk of over wear, lack of oxygen, or any other negative effect that extended wear (2-week or monthly) contacts can potentially have. While up-front costs of dailies are higher than their counterparts, there are significant savings in terms of manufacturer rebates. In addition, buying contact lens solution is no longer necessary! While a very small minority of patient prescriptions are not yet available in dailies, the majority are, and these contacts have worked wonders for patients who have failed in other contacts, especially those who have dry eyes. Ask your eye care professional how dailies might be the right fit for you. Article contributed by Dr. Jonathan Gerard

Sunglasses are more than just a fashion statement - they’re important protection from the hazards of UV light. If you wear sunglasses mostly for fashion that’s great--just make sure the lenses block UVA and UVB rays. And if you don’t wear sunglasses, it’s time to start. Here are your top 6 reasons for wearing sunglasses: Preventing Skin Cancer One huge way that sunglasses provide a medical benefit is in the prevention of skin cancer on your eyelids. UV light exposure from the sun is one of the strongest risk factors for the development of skin cancers. Each year there are more new cases of skin cancer than the combined incidence of cancers of the breast, prostate, lung and colon. About 90 percent of non-melanoma skin cancers are associated with exposure to ultraviolet (UV) radiation from the sun. Your eyelids, especially the lower eyelids, are also susceptible to UV light and they do develop skin cancers somewhat frequently. Many people who now regularly apply sunscreen to help protect them from UV light often don’t get that sunscreen up to the edge of their eyelids because they know the sunscreen is going to make their eyes sting and burn. Unfortunately, that leaves the eyelids unprotected. You can fix that by wearing sunglasses that block both UVA and UVB rays. Decreasing Risk For Eye Disease There is mounting evidence that lifetime exposure to UV light can increase your risk of cataracts and macular degeneration. It also increases your risk of getting growths on the surface of your eye called Pinguecula and Pterygiums. Besides looking unsightly, these growths can interfere with your vision and require surgery to remove them. Preventing Snow Blindness Snow reflects UV light and on a sunny day the glare can be intense enough to cause a burn on your corne--much like what happens when people are exposed to a bright welding arc. Protection From Wind, Dust, Sand Many times, when you are spending time outdoors and it is windy, you risk wind-blown particles getting into your eyes. Sunglasses help protect you from that exposure. The wind itself can also make your tears evaporate more quickly, causing the surface of your eye to dry out and become irritated, which in turn causes the eye to tear up again. Decreasing Headaches People can get headaches if they are light sensitive and don’t protect their eyes from bright sunlight. You can also bring on a muscle tension headache if you are constantly squinting because the sunlight is too bright. Clearer Vision When Driving We have all experienced an episode of driving, coming around a turn, looking directly into the direction of the setting or rising sun, and having difficulty seeing well enough to drive. Having sunglasses on whenever you are driving in sunlight helps prevent those instances. Just a general reduction in the glare and reflections that sunlight causes will make you a better and more comfortable driver. So it’s time to go out there and find yourself a good pair of sunglasses that you look great in and that protect your health, too. Your eye-care professional can help recommend sunglasses that are right for your needs. Article contributed by Dr. Brian Wnorowski, M.D.
