The retina is the layer inside your eye that detects light and converts it into signals your brain can use. It’s critical for your vision.
Retina of the Eye: What It Is, Function & Anatomy - Cleveland Clinic
The retina (from Latin rete 'net'; pl. retinae or retinas) is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs. The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual ...
The retina is an essential part of the anatomy of the eye. It’s a light-sensitive layer at the back of the eye that sends electrical impulses to the brain.
Find out what you need to know about the retina, including where it's located, what it does, and potential health problems.
Retina, layer of nervous tissue that covers the inside of the back two-thirds of the eyeball, in which stimulation by light occurs, initiating the sensation of vision. The retina is actually an extension of the brain, formed embryonically from neural tissue and connected to the brain proper by the optic nerve.
