---|---|---|---|---|---|
low frequency visible flicker | Yes | Yes without PFC | some have | No | Cause myopia; headaches, migraines, fatigue, epilepsy, and other neurological responses; Degrade reading performance;provide a distraction or annoyance for sensitive individuals. |
infrared | Yes | No | Some have | No | ocular lens damage, continuous wave retinal damage; lens protein denaturation and cataracts This is photothermal damage. |
peak strong light | Yes | Yes | Some have | No | keratitis (corneal epidermal necrosis, loss), eye pain, photophobia and tearing. Injury to corneal, lens, retina; Vitreous injury;dry eye; photoreceptor cell damage; age-related macular degeneration; macular retinal choroidal damage. |
ultraviolet | No | Yes | Some have | No | cataract,premature presbyopia,Pterygion; Retinal degeneration, retinal damage,photochemical lesions in the neural retina and retinal pigment epithelium; macular disease, blurred vision and image distortion symptoms. Chronic blepharitis, conjunctivitis, conjunctival elasticity and gloss loss, and pigment hyperplasia. UV-induced electric photophthalmia; customary system electric ophthalmia, the ultraviolet radiation keratoconjunctivitis. Skin aging black or skin cancer;This is photochemical damage. |
unsafe electromagnetic raidiation | Yes | Yes | Some have | No | 1)cell carcinoma induction; 2)abnormal hormone; 3)intense calcium loss; 4) triggering dementia; 5)abnormal pregnancy and abnormal birth; 6)high blood pressure and heart disease; 7) electromagnetic hypersensitivity; 8) depression increase. |
high frequency invisible flicker | No | Yes | Yes | No | Retinal degeneration,Choroidal neovascularization,photomechanical damage;headaches and eye strain. |
low frequency ripple flicker | Yes | Yes | Yes | No | Cause myopia; headaches, migraines, fatigue, epilepsy, and other neurological responses. Degrade reading performance, provide a distraction or annoyance for sensitive individuals. |
unsafe blue light | Yes | Yes | Yes | No | veiling glare intense enough to degrade visual performance,macular degeneration and other vision problem, photochemical damage and apoptotic cell death, and retinal injury. Blue light induce damage to retinal pigmented epithelial cells. |
dimming high frequency flicker | Yes | Yes | Yes | No | Retinal degeneration,Choroidal neovascularization,photomechanical damage |
