Blue light explained

What is blue light?

Blue light is a type of light that sits between harmful UV light and less harmful visible light in the electromagnetic spectrum. It has the highest energy and shortest wavelength of all light in the visible spectrum, which makes it more damaging. Blue light is present in both natural and artificial sources, such as the sun and screens of electronic devices. Exposure to high energy blue light can be beneficial for regulating circadian rhythm and increasing alertness and mood, but too much exposure later in the day can disrupt sleep and contribute to digital eye strain and macular degeneration. Blue light glasses have special anti-reflection filters that block a portion of the high energy blue light emitted by electronic devices, which can reduce digital eye strain and improve contrast on screens. They can be worn by anyone who uses electronic devices frequently and can be prescribed or non-prescribed.
