Learn about the various observable events that result from the interaction of light and matter in nature, such as rainbows, halos, auroras, and mirages. Explore the different types of optical phenomena, their causes, and their examples with images and references.
Learn about visual perception, the ability to interpret the environment through different types of vision, such as photopic vision (daytime vision) and scotopic vision (night vision). Explore the history, physiology, and psychology of vision science, from ancient theories to modern research.
Flash blindness is a temporary or permanent visual impairment caused by exposure to a very bright light source, such as a nuclear explosion, flash photograph, lightning or laser. Learn how flash blindness works, how it differs from other conditions, and what potential hazards it poses in various situations.
Charman et al. (1971) asked whether the LF were the result of single cosmic-ray nuclei entering the eye and directly exciting the eyes of the astronauts, as opposed to the result of Cherenkov radiation within the retina. The researchers had observers view a neutron beam, composed of either 3 or 14 MeV monoenergetic neutrons, in several ...
Learn about the factors that determine eye color in humans and other animals, such as pigmentation, scattering, and genetics. Explore the range of eye colors, from brown to blue, and their medical implications, such as Wilson's disease and albinism.
Refraction is the redirection of a wave as it passes from one medium to another, such as light in air, water or glass. Learn how refraction depends on the wave speed, the angle of incidence and the refractive index, and see how it affects phenomena like rainbows, prisms and optical devices.
Learn how blue light, a type of short-wave light in the violet / blue band, can affect circadian rhythm, retinal health, and sleep quality. Find out the sources, evidence, and controversies of blue light exposure and filtering.
Learn about the anatomy, physiology and optics of the human eye, a sensory organ that allows vision and other functions. The eye is composed of several layers, including the cornea, iris, lens, retina and sclera, and has various muscles and nerves that control its movements and responses.
