High-acuity vision is mediated by the
WebVisual acuity is a measure of the spatial resolution of the visual processing system. VA, as it is sometimes referred to by optical professionals, is tested by requiring the person whose vision is being tested to identify so-called optotypes – stylized letters, Landolt rings, pediatric symbols, symbols for the illiterate, standardized Cyrillic letters in the … WebRods & Cones. There are two types of photoreceptors in the human retina, rods and cones. Rods are responsible for vision at low light levels ( scotopic vision ). They do not mediate color vision, and have a low spatial acuity. Cones are active at higher light levels ( photopic vision ), are capable of color vision and are responsible for high ...

Web'Ocular tracking' refers to visually driven, slow eye movements that stabilize moving images on the retina, thereby facilitating high acuity vision. Recent behavioral studies have shown that the primate brain produces several kinds of ocular tracking responses that operate precisely and consistently, with ultra-short latencies.
