As we evolved, our eyes gradually adapted to natural light sources. In the last 100 years, various artificial light sources have been produced due to technology, which has rapidly changed with each passing day. These new artificial light sources will produce quite a lot of blue light. Blue light can account for more than 26% of the light emitted from increasingly popular tech, like fluorescent lights, smartphones, televisions, and computer screens. Blue light penetrates the cornea and lens, directly to the macular area, this can accelerate the oxidation of cells in the macular area, causing chemical damage to the retina. This is also the main reason why many older people suffer permanent loss of vision in their later years. The fast-paced life exposes us to constant exposure to blue light. Long Term use of mobile phones, computers, and various types of electronic products can result in dry eyes, blurred vision, visual fatigue, and pain in the heads.

1. They reduce eye strain. Working with a computer or smartphone all day can cause problems, like eye strain and even loss of sleep. Using blue light blockers will reduce eye fatigue, headaches, and blurred vision.
