Visible light is actually composed of several different wavelengths depending on the color. Blue light is anything that falls between 450 and 495 nm. It is characterized as having high energy. This is emitted by various devices that are common in today’s world including computer monitors, smartphones, television sets, and lighting fixtures. It can be good in small amounts with effects including increased alertness and improved mood.
However, it can also be detrimental to health especially with long and excessive exposure. It can mess up one’s circadian rhythm and trigger various sleep disorders. Sensitive regions of the eyes can also suffer resulting in poor vision. Eyestrain is also common among workers, students and gamers. Among the proposed solutions is to wear blue light filter glasses that can block much of it from entering the eyes. This allows people to work longer in comfort.
