Digital devices such as cell or mobile phones, computers, tablets and televisions emit primarily blue light, excessive exposure to which may affect your risk of age-related macular degeneration and blindness. Dr. Joseph Mercola shares simple and easy strategies to reduce your risk.
Before the invention and distribution of artificial lighting, the sun was the major source of light and determined how people spent their evenings. It is easy to take for granted the extended days and added lighting. However, humans and animals are paying a price as it throws off circadian rhythms, interrupts sleep and affects the development of disease and perpetuation of animal species.
One pervasive light source comes from digital devices, which become more popular every year. Mobile device use varies, but research shows desktop device use is important during daytime hours and mobile use increases in the evenings and at night.1
Statistics show that 77% of Americans own a smartphone, 75% own a laptop or desktop computer and 50% own tablets; 20% of Americans are smartphone-only internet users and 25% of US adults say they are “almost always” online.2
Research demonstrates how blue light emitted from your favourite digital device may be speeding up eye damage and accelerating macular degeneration (“AMD”), the leading cause of blindness.3 Before sharing specifics of how blue light interacts with your eye, let’s quickly review some important eye structures and nutrients for eye health.
