Blind Spot/Vision

Rods

-are a visual receptor that has a rod-shaped outer part and functions in dim light. -located mostly in the peripheral regions -can detect motion, but not specificity. -can pick up the contrast between dark and light, but not color. -Used for night or in darkness. (100 million/eye)

Cones

-have a cone shaped outer part -function in high-intensity light -color vision. (10 million/eye) -activated by high intensity light -provide precise visual acuity -color recognition -concentrated in the posterior part of retina.

Macula Lutea

-is a rounded yellowish region that is lateral to the blind spot. The very center of it is called the Fovea Centralis which is the area with the sharpest vision

Optic Disc (Blind Spot)

-is found in an area where the optic nerve exits the eye. This area contains no photoreceptors and therefore there is a blind spot.
