FAQs
Do blue light glasses really work?Yes. Blue light blocking glasses have filters that harmful block blue light waves given off by any light source -- the sun, screens, lightbulbs, etc. That means if you use these glasses when looking at a screen, especially after dark, they can help reduce exposure to blue light waves that can keep you awake and also help reduce eye strain.
Are blue light glasses safe and effective?Blue light is high energy light which can cause damage to eyes and skin after using digital devices all day. But using blue light blocking glasses is a safe move and can never hurt eyes unless you filter and block light incorrectly. But different blue light glasses may not filter out the same amount of blue light, the least expensive one might block the most amount of blue light. Even though blue light glasses don't filter out all blue light, they do reduce exposure to blue-violet rays by 80 percent or more.
