Pupils will dilate at dark place and will constrict at a bright place. Pupils will dilate and constrict with the variation of the flicker light with low frequency. Eye muscles become fatigue,
or even loose and cannot adjust pupils to see distant object leading to myopia.For high frequency flicker light, pupils can not dilate or constrict with fast flicker variation.
Peak strong light irradiate the retina. Retina degeneration is produced.
Ultraviolet cause cataract, infrared cause retinal damage, hazard blue light cause macular degeneration.
low frequency flicker light: cause myopia
infra red:continuous wave retinal damage; lens protein denaturation
high frequency flicker light: retinal degeneration
peak strong light on retina: photoreceptor cell damage
ultra violet: cataract
high frequency flicker light: retina degeneration
unsafe blue light: macular degeneration
strong green or red light: cause myopia
