UV Protection
The ability of something to block harmful ultraviolet rays from the sun.
What is it?
UV protection means stopping ultraviolet (UV) light from reaching your skin or eyes. UV rays can cause sunburn, eye damage, and even skin cancer. Sunglasses with UV protection have special coatings that block these rays. The first UV-blocking sunglasses were developed in the 1930s. Today, many sunglasses are labeled with UV400, which means they block 99% of UV rays. The child's reflection mentions that modern sunglasses protect eyes from UV damage, showing awareness of this important function.
Why it matters
Wearing sunglasses with UV protection keeps your eyes healthy. It also helps prevent cataracts and other eye problems later in life.
