Diving into the Blue: A Top Five Guide to Understand the Impact of Blue Light on Eye Health

Blue light is a part of the visible light spectrum. Its short-wavelength frequency makes it a high-energy visible (HEV) light.

While some exposure to blue light is necessary for maintaining good health and regulating the body's sleep-wake cycle, excess exposure, especially from artificial sources, can have adverse effects.
