Blue Light Filter Lenses: The Problem

So… What’s the problem with blue light? Light is scattered by gas molecules in the air; the shorter the wavelength of light, the more it is scattered. Because of its shorter wavelength, blue light is scattered ten times more than red light. Additionally, rods in the eye have different levels of sensitivity, and blue light focuses too far in front of the retina for them to reach. Have you ever noticed that it is hard to focus on sources of blue light? The edges get fuzzy and cause a halo effect, especially at night, even when other colors next to it look sharp? That bright blue LED light, which is also given off by many electronic devices, may be the cause of eye strain, headaches, and even sleep disruption.
