Ultraviolet (UV) rays are emitted by the sun in three forms: UVA, UVB and UVC. While UVC is absorbed by the earth’s atmosphere, UVB radiation is only partially blocked. UVA radiation is not blocked at all and can burn the skin and eyes, as per the World Health Organization. Many adults report experiencing the following symptoms after prolonged UV exposure: irritation in the eye, trouble seeing, wrinkles around the eyes, red or swollen eyes, sunburn of the eyelids and eye, and, in some cases, cancer on or around the eyes.
Since UV rays are always present, 20Twenty Eyecare encourages everyone to wear UV-protective eyewear whenever they’re outdoors during daylight hours, no matter the season or weather. Adults and children should have a comprehensive annual eye exam, as an eyecare provider can make recommendations regarding UV-protective eyewear tailored to an individual’s vision and lifestyle needs.
