Blue light is a color in the visible light spectrum that can be seen by human eyes. The most potent harmful blue light is known as high energy visible light (HEV), which induces retinal damage and contributes towards inflammation of the skin. Even “good” blue light, which is useful for various treatments (sleep disorders, seasonal depression, etc.) can be harmful with prolonged exposure.

Blue light penetrates your retinas, giving your brain a cue that it’s time to wake up and seize the day. By restricting the production of melatonin (a chemical that helps us sleep), blue light disrupts your natural sleep cycles causing you to feel lethargic, irritable, and unproductive. Extended exposure to blue light from an iPhone or other device can have a significant impact on our wellbeing – headaches, eye irritation and fatigue are all common symptoms of blue light exposure.
