Blue Light FAQ
Where does blue light come from?
You encounter blue light in everyday activities. Fluorescent lighting, electronic screens (phones, tablets, computers, TVs, etc.), and the sun emit damaging high-energy blue light. Unlike ultraviolet light, which is filtered by the cornea and crystalline lens, blue light is the highest energy light that actually makes it to the back of the eye and our retina. Our eyes have no natural protection in our younger years.
Is there good blue light?
Not at night. According to Harvard reasearchers, even dim light can interfere with a person’s circadian rhythm and melatonin secretion. “A level of brightness of about twice that of a night light has an effect.”
