The blue light from devices can penetrate the protective layers of your eyes and result in dry eye, cataracts, and macular degeneration.
Exposure to blue light at night reduces melatonin synthesis, which in turn reduces the quality of sleep, according to new research published in Chronobiology International.
Pain or stiffness in the shoulders, arms, and hands can be the result of poor posture, tension in the neck and shoulders, digital eye strain, or overuse injuries.
In fact, that's only the beginning. Experts have shown that prolonged exposure to blue light might have negative effects on the skin.
Blue light can pass through the skin. Blue light, like ultraviolet (UV) light, can cause long-term damage, says dermatologist Rebecca Marcus, MD.
"We may not detect any short-term impacts, but it's undoubtedly leading to collagen degradation, wrinkles, and hyperpigmentation," says Dr. Marcus.
Another study published in the Journal of Investigative Dermatology associated blue light with photoaging, pigmentation problems, and melasma.
The Journal of Cosmetic Dermatology says that long-term contact may weaken the barrier of your skin. The skin can become sensitive, dry, red, and break out.
In short, there is evidence that long-term exposure to blue light without protection could cause sagging, wrinkles, discoloration, and sensitivity in the skin.
