Answer 1

Blue light from your computer and phone will keep you awake and may affect your mood. In theory, they would also cause problems like macular degeneration and cataracts. However, exposure from the sun is many times greater than the exposure form your computer or phone. Sunglasses may filter out blue rays but they also filter out a lot of other light needed to see your computer comfortably. You may have a setting on your device that will minimize blue light exposure. Non-prescription blue light blockers are available for about the price of sunglasses. Transitions blocks blue light as well as changing into sunglasses outside.
