The key retina parts include the rods and cones, which convert light into electrical signals for the brain, and the macula, which allows you to see details clearly. ... The surface of the eye.
Cones are sensitive to color, but less sensitive to light — i.e. in darker conditions, you’re seeing more with rods than cones. You have three sizes of cones, blue (smallest) to red (biggest ...
