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 in artificial narrowband form has a number of proven negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related ...
The retina is located at the back of the eye. Blue light can induce photochemical damage to the retina by passing through lenses and into the retina. Two primary types of cells contribute to vision formation within the retina: photoreceptors (including rod and cone cells), and retinal pigment epithelium (RPE) cells. [16]
A number of computer and smartphone applications adjust the computer video color temperature, reducing the amount of blue light emitted by the screen, particularly at night. Dry eye is a symptom that is targeted in the therapy of CVS. The use of over-the-counter artificial-tear solutions can reduce the effects of dry eye in CVS.

"Exposure of the retina to intense visible light causes damage to its light-sensitive rod and cone cells," Dr. Ralph Chou at the University of Waterloo in Canada said on his website."The light ...
According to the American Academy of Ophthalmology, there is no scientific evidence showing that exposure to blue light emitting devices result in eye damage. [74] According to Harriet Hall, blue light exposure is reported to suppress the production of melatonin, which affects our body's circadian rhythm and can decrease sleep quality. [75]
The condition primarily affects the retina, the light-sensitive layer at the back of the eye, and sometimes the optic nerve, which transmits visual signals to the brain. Following cataract surgery, the replacement of the natural lens with a synthetic one increases sensitivity to blue light, resulting in a blue-tinged visual field. Similarly ...
Millions of people are catching a glimpse of the solar eclipse — but the spectacle can lead to eye damage if you’re not careful. That’s because looking at the sun without eclipse glasses can ...
