Retina

The human retina lies on the back of the eye. Light enters the eye and is focused onto the retina by the lens.  The microscope shows 10 layers of the retina.

The photoreceptors, the rods and cones, lie deep in the retina. They detect black and white light and red, green and blue colours.

Bipolar, horizontal and amacrine cells transmit information from the photoreceptors to large ganglion cells whose long processes travel horizontally to the brain via the optic nerve.

Pigment epithelium forms the deepest layer, nourishing the photoreceptors and absorbing scattered light to reduce blurring.
