Sunglasses.
This is an area of eyecare that seems simple on the surface but is actually quite complex. Most people think of sunglasses as something that makes them look cool in the summertime. While this is true, it is not the only reason to wear sunglasses. The number one reason to wear sunglasses is for UV radiation protection. Ultraviolet light is a high wavelength high energy radiation that has an effect on several parts of the eye. First, it can cause ocular irritation and exacerbate dry eyes. UV light also causes cataracts; however, this is a cumulative effect so the all the times you ran around outside in your youth adds up and eventually causes cataracts in your later years. While not completely understood, there is also a link between UV and high energy blue light and macular degeneration.
OK, those are the boring medical reasons to wear sunglasses. Well, what kind should you wear? I always tell people that with sunglasses, you typically get what you pay for. A pair of high end polarized sunglasses will make everything sharper and reduce glare and eyestrain. A pair of 5 dollar cheapos will make you see like you have cataracts. The difference between the good lenses and the bad is the quality of the optics, since almost all sunglasses offer UV protection. Many times a pair of cheap lenses will warp and cause induced astigmatism, which can distort your vision. If you do any kind of outdoor activities, polarized lenses are a must. Polarization is a way to reduce glare off reflecting surfaces, such as water, roads, and windshields. Another great option for sunglasses is Transition lenses. These are the lenses that darken outside and lighten inside. They have the advantage of having your prescription in them so you can wear the same glasses for all activities. If you want to know if your sunglasses are any good, just bring them by and ask one of our opticians. Some of the expensive designer sunglasses popular with certain celebrities actually have poor quality lenses. We are able to take those lenses out and put in a pair of optical quality sunglass lenses. Now, go get a pair of sunglasses and enjoy your summer.
