If you spend a lot of time using your PC, especially at night, you may be exposing your eyes to harmful blue light. Blue light is a part of the visible light spectrum that has the shortest wavelength and the highest energy. It can cause eye strain, dry eyes, headaches, insomnia, and even damage your retina over time. It can also disrupt your natural sleep cycle by suppressing the production of melatonin, the hormone that regulates your circadian rhythm.
