You’re wearing cheap sunglasses.
Designer sunglasses aren’t just pricey because they are brand name buys. Expensive shades also tend to come equipped with 100 percent ultraviolet protection, guaranteeing that your eyes are completely shielded against the sun’s harmful rays.
Conversely, $10 sunnies sold at a street fair tend to just be tinted without total UV protection. This tinting “causes the pupil to dilate without UV blocking so more ultraviolet radiation is able to enter the eye,” Benjamin Bert, MD, ophthalmologist at MemorialCare Orange Coast Medical Center, explains.
