Laser blended vision. Laser blended vision is a laser eye treatment which is used to treat presbyopia (ageing eyes; [1] progressive loss of the ability to focus on nearby objects) or other age-related eye conditions. [1] It can be used to help people that simply need reading glasses, and also those who have started to need bifocal or varifocal ...
Abundant visible light to the eyes gives health benefits through its association with the timing of melatonin synthesis, maintenance of normal and robust circadian rhythms, and reduced risk of seasonal affective disorder. [10] On the negative side, UV is a mutagen and carcinogen for skin.

Eye tracking device is a tool created to help measure eye and head movements. The first devices for tracking eye movement took two main forms: those that relied on a mechanical connection between participant and recording instrument, and those in which light or some other form of electromagnetic energy was directed at the participant's eyes and its reflection measured and recorded.
Adaptation (eye) In visual physiology, adaptation is the ability of the retina of the eye to adjust to various levels of light. Natural night vision, or scotopic vision, is the ability to see under low-light conditions. In humans, rod cells are exclusively responsible for night vision as cone cells are only able to function at higher ...
For the simplified scenario of visible light travelling from air (n 0 ≈ 1.0) into common glass (n S ≈ 1.5), the value of R is 0.04, or 4%, on a single reflection. So at most 96% of the light (T = 1 − R = 0.96) actually enters the glass, and the rest is reflected from the surface. The amount of light reflected is known as the reflection loss.
