Do Blue Light Glasses Block UV Rays?: Find out the truth about blue light blocking and UV protection!

Blue light glasses are specially designed to filter out a portion of the high-energy blue light emitted from digital screens and artificial lighting. Their main purpose is to help reduce eye strain, improve sleep, and protect your eyes during prolonged screen time. However, whether they offer protection from ultraviolet (UV) rays is a separate concern. Most standard blue light glasses do not inherently block UV rays unless the lenses are specifically treated with a UV-blocking coating. UV rays, unlike blue light, are non-visible and can cause eye health issues such as cataracts and photokeratitis in the long run. If you're seeking protection from UV rays in addition to blue light, look for glasses that clearly state they offer both blue light filtering and UV400 protection, which ensures the lenses block 99-100% of UVA and UVB rays.

Tips 1:

As a designer, I always consider how comfort and aesthetics intersect when choosing accessories, including eyewear for the studio or home office. Selecting glasses with both blue light and UV protection not only safeguards your eyes but also supports productivity and well-being in your workspace. Integrating thoughtful tools like this is similar to selecting the right elements in a home office layout—each choice impacts your overall experience and efficiency.
