optic radiations

Physics; Color science

The bundles of axons projecting from the lateral geniculate nucleus to primary visual cortex.

Snellen acuity

Physics; Color science

Visual acuity as measured by the ability to discriminate high contrast shapes. The familiar Snellen eye chart which contains rows of letters each smaller than the one above provides one way of ...

neutral point

Physics; Color science

All dichromats will accept a match between some spectral light and a white light. The wavelength of this spectral light is the neutral point for that dichromat. No trichromatic subject, including ...
