Normalized responsivity spectra of human cone cells, S, M, and L types (SMJ data based on Stiles and Burch [1] RGB color-matching, linear scale, weighted for equal energy) [2] LMS (long, medium, short), is a color space which represents the response of the three types of cones of the human eye , named for their responsivity (sensitivity) peaks ...
Dark adaptation of both rods and cones requires the regeneration of the visual pigment from opsin and 11-cis retinal. [13] Therefore, the time required for dark adaptation and pigment regeneration is largely determined by the local concentration of 11-cis retinal and the rate at which it is delivered to the opsin in the bleached rods.

One of the more intriguing features Microsoft will include in this fall's Windows 10 Creators Update is Timeline. As the name suggests, it's a way for you to move backwards in time and see things ...
For the human eye, a piece of white paper looks white no matter whether the illumination is blueish or yellowish. This is the most basic and most important of all color appearance phenomena, and therefore a chromatic adaptation transform (CAT) that tries to emulate this behavior is a central component of any color appearance model.
[9] [10] He was the first person to explain that vision occurs when light bounces on an object and then is directed to one's eyes. [11] Leonardo da Vinci (1452–1519) is believed to be the first to recognize the special optical qualities of the eye. He wrote "The function of the human eye ... was described by a large number of authors in a ...
Interocular transfer (IOT) is a phenomenon of visual perception in which information available to one eye will produce an effect in the other eye. For example, the state of adaptation of one eye can have a small effect on the state of light adaptation of the other. Aftereffects induced through one eye can be measured through the other. [1] [2]
The normal human observer's relative wavelength sensitivity will not change due to background illumination under scotopic vision. The wavelength sensitivity is determined by the rhodopsin photopigment. This is a red pigment seen at the back of the eye in animals that have a white background to their eye called Tapetum lucidum.
The pupil of the human eye can range in size from 2 mm to over 8 mm to adapt to the environment. The human eye can detect a luminance from 10 −6 cd/m 2, or one millionth (0.000001) of a candela per square meter to 10 8 cd/m 2 or one hundred million (100,000,000) candelas per square meter.
