Document Summary

Cones: have more the red stuff in them. Duplex theory: we have two ways to gather information. Rods: operate of low level of light intensity, sensitive for brightness. None in fovea, mostly in the peripheral retina. Cones: operate at higher intensities: insensitive for brightness. Concentrated in the fovea, full in colours we mostly use cones vision pigments. The colours that they have are visual pigments/photo rhodopsin. No exposure: reddish cherry, with light: orange, bleach (breaking down all the rhodopsin) going to break down and indicating the colours. Cones: have one of three: chlorolabe (green), erythrolabe (red), cyanolabe (blue) they are: dark adaptation: completely dark bleach the eyes by splash a light and measure. Have to look directly at the light: spectral sensitivity: some cones response only to the certain colour of lights when we gonna see the light. The spots do not exist, but they are there, which is related to the way we process visual.
