Retinal damage. sunlight contains UV and blue light. Blue light, which is part of the visible light spectrum,it reaches deeper and deeper into the eye and its progressive effect can cause damage to the retina.
Sleep deprivation.... research shows that the shorter wavelengths in blue light is what causes the body to produce less melatonin because it is sensitive to this type of light. ... Other wavelengths suppress delta brainwaves, which persuades sleep, and boost alpha wavelengths, which create alertness.
Blue light is also associated with:
1. Increased risk of diabetes,fatness and heart disease.
2.Higher prevalence of certain cancers.
3.Increased possibility of depression.
