Eyeball layers
The layers of the eye form the wall of the eyeball. They can be roughly divided into three areas: the outer membrane with the cornea and sclera, the middle membrane with the iris, choroid, and ciliary body, and the inner membrane with the photoreceptive and blind parts of the retina.

Bipolar cells
The bipolar cell is a bipolar neuron, i.e., a neuron with one axon and one dendrite located in the middle layer of the retina. It transmits sensory information from the photoreceptors to the ganglion cells.
