Helpful Hints for Selecting Sunglasses
At Longe Optical, we are passionate about eye care, which includes the eyewear we wear during the summer months! Many of our customers don’t realize how important sunglasses are and that they function as more than just a fashion accessory. When shopping for sunglasses, it’s important to understand exactly what types of UV protection you are looking for and what might happen to your eyes if you’re not properly protected.
Types of UV Radiation
The sun emits two major types of UV radiation that can cause damage to the eye: UV-A and UV-B. Overexposure to UV-A radiation can damage the macula, hurting your central vision. Too much UV-B radiation exposure can lead to damage in the corona and the lens of your eye.
When picking out a stylish pair of glasses, Longe offers a wide variety of frames that also provide protection for your eyes at an affordable price. It’s important when you’re looking for a good pair of sunglasses to not just grab the cheap promotion glasses you got from a local parade: quality is important. When looking for a pair, make sure your glasses say “100% protection against UV.” A pair of glasses that just says UV protection most likely will rub off after one cleaning, as the UV protection is just coated over the lenses, not embedded into it.
Not all polarized lenses provide active UV protection! Polarized lenses have a unique chemical coating that is designed to reduce glare from reflected light. Although it is true that polarized glasses and UV protection are often paired together in high-quality glasses, this is not always the case. Many cheap polarized sunglasses on the market don’t have any UV protection which is why checking for 100% protection in your pair is important.
Prolonged unprotected exposure to UV rays can lead to cataracts, pterygium, and macular degeneration in the human eye. Cataracts involve a clouding of the eye’s lens resulting in blurred vision; pterygium involves painful tissue growth on the eyeball; and macular degeneration leads to destroyed central vision when the macula in the retina deteriorates. If not prevented, these conditions can require surgery or cause loss of vision.
Although serious conditions in your eye might not be occurring now, be sure to schedule your annual eye exam today and while you’re here, pick up some stylish sunglasses with lenses that will both protect your eyes and keep you looking great this summer!
