flicker light
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, infrared, hazard blue light
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
- Role: CSS/XHTML
- La Trobe University in Anstralia found low frequency temporal modulation of light promotes a myopic shift
- cyclic intensive light exposure induces retinal lesions similar to age-related macular degeneration
- IEEE research have shown high frequency flicker may lead to headaches and eye strain
- Uppsala University in Sweden found that near infrared radiation may cause cumulative damage in the ocular lens.
- Fordham University, New York City found Ultraviolet radiation as a risk factor for cataract,macular degeneration and retinal damage.
- University of Texas Southwestern medical center in Texas found strong blue light can cause macular degeneration and other vision problem
