What is blue light? "Blue light is emitted from all handheld electronic devices as well as desktop and laptop computers and televisions," says leading holistic eye physician Dr. Marc Grossman. "It's the shortest wavelength light in the visible spectrum and causes significant damage to many parts of the eye, seriously impacting present and future vision capacity. Damage from blue light from smartphones is particularly important because smartphones are often used in dim light and are used close to the eyes. Unlike ordinary computer vision fatigue, damage from blue light is serious, cumulative and irreversible."
RealSelf contributor Dr. Joel Schlessinger adds that the sun also emits a big chunk of the blue light we're exposed to. That's right, the sun can do damage beyond skin cancer and wrinkles and with our ever-increasing reliance on technology, blue light exposure is only increasing.
