1. Damage to Vision

3. Glare

HOW MUCH BLUE LIGHT SHOULD YOU FILTER?
You should filter only as much as you need to reduce the threat. First look at how much time you spend in front of your devices at night and use the MPF rating that is most appropriate.

WHY USE COMPUTER GLASSES?
Based upon scientific studies, it is known that after 2 hours staring at the iPad late at night, there is a reduction in the rate of melatonin production by as much as 22%.

After clearly identifying the problem and developing a patented system of measuring the effects of blue light on the body’s production of hormones that promote sleep, time came for testing ways to solve the problem.
