In ocular physiology, adaptation is the ability of the eye to adjust to various levels of light.
Amacrine cells are interneurons in the retina.
The Ancient Greek language includes the forms of Greek used in ancient Greece and the ancient world from around the 9th century BC to the 6th century AD.
Averted vision is a technique for viewing faint objects which uses peripheral vision.
The candela (or; symbol: cd) is the base unit of luminous intensity in the International System of Units (SI); that is, luminous power per unit solid angle emitted by a point light source in a particular direction.
Cone cells, or cones, are one of three types of photoreceptor cells in the retina of mammalian eyes (e.g. the human eye).
Deilephila elpenor, also known as the elephant hawk moth, is a moth in the ''Sphingdae'' family.
A ganglion cell is a cell found in a ganglion.
The human eye is an organ which reacts to light and pressure.
Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum.
Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction.
Mesopic vision is a combination of photopic vision and scotopic vision in low but not quite dark lighting situations.
Night vision is the ability to see in low-light conditions.
Photopic vision is the vision of the eye under well-lit conditions (luminance level 10 to 108 cd/m2).
Photopigments are unstable pigments that undergo a chemical change when they absorb light.
The Purkinje effect (sometimes called the Purkinje shift) is the tendency for the peak luminance sensitivity of the human eye to shift toward the blue end of the color spectrum at low illumination levels as part of dark adaptation.
Rhodopsin (also known as visual purple) is a light-sensitive receptor protein involved in visual phototransduction.
Rod cells are photoreceptor cells in the retina of the eye that can function in less intense light than the other type of visual photoreceptor, cone cells.
In mathematics, physics, and engineering, spatial frequency is a characteristic of any structure that is periodic across position in space.
The tapetum lucidum (Latin: "bright tapestry; coverlet", plural tapeta lucida) is a layer of tissue in the eye of many vertebrates.
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye.
Visual acuity (VA) commonly refers to the clarity of vision.
Visual perception is the ability to interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment.
