The eye - Photoreceptors

2 types: rods and cones
Rods are filled with rhodopsin
3 types of cones for red, green and blue light (colour vision)
Rods are for nighttime vision and cones for daytime.
Rods are more sensitive to green and cones to yellow
Cones are mostly concentrated in the fovea while rods mostly outside of it (absent from the fovea)
There are no blue cones in the fovea
Ganglion cells and blood vessels leave the eye through the blind spot
Colourblind people have unusual arrangements with either their red or green cones
This book is ridiculous
