More than just an accessory—sunglasses protect your eyes from the sun’s harmful side effects.
Apr 26, 2018
As warmer, sunnier weather approaches, many of us have begun to trade in our winter coats for shorts and sunscreen. While it’s important to protect our skin from harmful ultraviolet (UV) rays, our eyes are just as susceptible to damage if not protected properly. Below are a few reasons why a stylish pair of protective shades are important for more than just accessorizing.
Seeing the World Comfortably
The perfect pair of sunglasses can complement a great outfit, but can also prevent the sun from hampering our eyes’ ability to adjust to lower light levels, and uncomfortable squinting caused by extended time in bright sunlight.1
Protection Against Harmful UV Rays
Extended exposure to UV-A and UV-B rays can contribute to cataracts, (clouding of the eye’s lens that can blur vision), and it is estimated that 20 percent of cataracts cases are caused by extended exposure to UV rays.2 Rocking a proper pair of shades can help reduce the risk of cataracts, and prevent photokeratitis (sunburn of the eye), as well.3
Absorption of HEV Radiation
UV rays aren’t the only type of radiation that can damage your eyes. High-energy visible (HEV) radiation can increase your risk of macular degeneration over time, damaging the retina and causing a loss of central vision.2, 4 Sunglasses that absorb these rays can reduce the risk of retinal damage and keep your maculae in tip-top shape.3
What to Look For
In order to properly protect your eyes from the sun, you should look for a pair of shades that block out 99 to 100 percent of both UV-A and UV-B rays, and absorb most HEV rays.3 Additionally, frames with a close-fitting wraparound style, and lenses with a uniform tint throughout can also keep harmful side effects of extended sun exposure at bay.1,3
