The Problem As we understand we will be spending our future on devices every day mostly on phones. We hold phones close to our eyes causing eye burns from harmful blue lights which leads to many complications like blurry eyes, red eyes, dry eyes, eye floaters, and eye twitching. This problem is real and it is happening to everyone. This glass is a precaution for your safe future with devices. Let's be responsible and take precautions for you and your family. By using this Zero Eye Strain,™ your eyes will be protected from eye complications and it reduces strain on eyes up to 70-80% depending from person to person. Blue light reaches deeper into the eye and its cumulative effect can cause damage to the retina. Furthermore, in certain wavelengths, blue light is implicated in the development of age-related macular degeneration (AMD). Because of their shorter wavelengths, these “Blue” or High Energy Visible (HEV) wavelengths flicker more easily than longer, weaker wavelengths.This kind of flickering creates a glare that can reduce visual contrast and affect sharpness and clarity.
