Peripheral and foveal vision
WebNov 1, 2024 · Peripheral vision can be tested using a "confrontation visual field test." First, a doctor stands in front of the person being tested and has them focus on one area, such as the doctor's headgear. The person being tested covers one eye, and the doctor raises different numbers of fingers in the person's peripheral vision. http://hyperphysics.phy-astr.gsu.edu/hbase/vision/rodcone.html

To them is attributed both color vision and the highest visual acuity. Visual examination of small detail involves focusing light from that detail onto the fovea centralis. On the other hand, the rods are absent from the fovea.

WebThey detect dim light and are used primarily for peripheral and nighttime vision. Cones are weakly photosensitive and are located near the center of the retina. They respond to bright light, and their primary role is in daytime, color vision. The fovea is the region in the center back of the eye that is responsible for acute vision.
