Blue light from digital devices damages eye cells

The video discusses the impact of blue light on the eyes, highlighting that it cannot be blocked or reflected by the cornea or lens. Photoreceptor cells in the retina use retinal to detect light, enabling vision. A study from the University of Toledo reveals that blue light exposure causes a toxic reaction in retinal, leading to the death of photoreceptor cells, which cannot regenerate. Vitamin E, specifically alpha tocopherol, can reduce cell damage, but its levels decrease with age. Prolonged exposure to blue light may result in macular degeneration, a major cause of blindness.
