Blue light harms our vision by damaging the eye's retina. The study found blue light turns a molecule in the eye into a cell-killing poison. It kills photoreceptor cells, which do not regenerate.
Studies have been conducted on blue light filtering eyeglasses, [5] [27] which uses special blue light blocking lenses for eye protection against blue light. [ 27 ] [ 28 ] All visible light wavelengths can be transmitted through the spectacle lens, [ 28 ] but some portions of the blue-violet light spectrum are selectively attenuated by coating ...
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.
One eye (left, amber filter) receives the cross-spectrum color information and one eye (right, blue filter) sees a monochrome image designed to give the depth effect. The human brain ties both images together. Images viewed without filters will tend to exhibit light-blue and yellow horizontal fringing.
Excessive blue light can cause accelerated aging in flies because this exposure can cause cellular damage, according to a study released Wednesday.
In a technique known as blue field entoptoscopy, the effect is used to estimate the blood flow in the retinal capillaries.The patient is alternatingly shown blue light and a computer generated picture of moving dots; by adjusting the speed and density of these dots, the patient tries to match the computer generated picture to the perceived entoptic dots.
Haidinger's brush, more commonly known as Haidinger's brushes is an image produced by the eye, an entoptic phenomenon, first described by Austrian physicist Wilhelm Karl von Haidinger in 1844. Haidinger saw it when he looked through various minerals that polarized light. [1] [2] Many people are able to perceive polarization of light. [3]
