A lens with a blue light glasses coating will divert blue light from entering your eye. It might seem like a small difference, but this barely noticeable coating makes a big impact in blocking out incoming blue light rays. It's powerful enough to protect your eyes from the adverse effects of blue light, and will still let you view other types of light with accuracy

Long-term exposure to blue light can have some pesky side effects. One of them being the disruption of your sleep schedule. When blue light penetrates your cornea, it reduces the amount of melatonin that your body produces. The bright light of your phone or computer screen convinces your body that it might still be day-time. This prevents you from getting a proper night’s rest. Got a friend or family member who’s work life revolves around the use of a computer? Ask them and they’ll know. A persistent mix of drowsiness and restlessness is common for folks that work long hours at a computer desk.

Headaches and disorientation are more common symptoms. We’ve all experienced it at some point in our lives. After working at your computer for a couple hours, you stand up and look away from your device. Everything around you becomes blurry and hard to focus on. This happens because prolonged exposure to blue light makes it harder for us to perceive other types of light. This can deteriorate our vision in both the long and short-term.
