Blue light is a form of high-energy visible light (HEV) that's emitted by screens and electronic devices. Unlike other forms of light, blue light has a shorter wavelength, which means it's able to penetrate deeper into the eyes. This can lead to a number of issues, including eye strain, headaches, and even a disruption of your circadian rhythm.

Your circadian rhythm is essentially your body's internal clock. It's responsible for regulating your sleep patterns, making you feel drowsy at night and alert during the day. When your circadian rhythm is disrupted, it can result in a number of negative effects, including insomnia, fatigue, and even depression. Exposure to blue light can disrupt your circadian rhythm by suppressing the production of melatonin, a hormone that's responsible for promoting sleep.
