Sunlight, or white light, is a spectrum of all colors of light. This spectrum ranges from low energy to high energy and red to blue colored light. Lately, there has been a lot of chatter about blue light and its deleterious effects on our health. We are exposed to blue light every day from the sun, light bulbs, and computer screens.

A great way to protect your skin from visible light, including blue light, is to use a tinted sunscreen containing iron oxide, in addition to other sun-protective behaviors.”
