The primary causes include post-cataract surgery, certain medications, and, less commonly, neurological or ophthalmological conditions. Post-cataract surgery is a common cause, as replacing the natural lens with a synthetic one increases exposure to blue light, leading to temporary blue-tinted vision. This effect usually resolves as the eye adapts.
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
Blue light is absorbed by the lens, preventing blue light from reaching the retina at the back of the eye. [12] To prevent retinal damage, the lens has to lower transparency. [ 9 ] This reaction causes visual impairment and the development of cataracts , [ 13 ] [ 14 ] a cloudy region in the lens.
Blue light emissions from intense sunlight exposure have been linked to macular degeneration, risk of cataracts and some other eye conditions — but electronics aren't known to emit enough blue ...
At some point—usually as you enter middle age—most people develop this eye condition, which is a clouding of the eye’s lens that can get progressively worse and impair your vision.
Filters Harmful Blue Light. ... May Lower the Likelihood of Cataracts. Cataracts, which cause clouding of the eye’s lens, are the world’s leading cause of blindness. As with AMD, oxidative ...
Ultraviolet light, specifically UV-B, has been shown to cause cataracts and there is some evidence that sunglasses worn at an early age can slow its development in later life. [18] Most UV light from the sun is filtered out by the atmosphere and consequently airline pilots often have high rates of cataracts because of the increased levels of UV ...
Dr. Kelley says that blue light or anti-reflective coatings may provide additional eye relief, sharing, "If you are nearsighted, farsighted or have astigmatism, you can get prescription blue light ...
