retina
(anatomy) the sensory membrane at the back of the eye that transmits light signals to the brain through optic nerves
What is "retina"?
The retina, located at the back of the eye, is a thin, light-sensitive layer that plays a crucial role in vision. It contains specialized cells called photoreceptors, including rods and cones, which convert light into electrical signals. These signals are then transmitted to the brain through the optic nerve, where they are processed and interpreted as visual information. The retina's intricate structure and arrangement of photoreceptor cells enable the perception of colors, shapes, and details, forming the foundation of visual perception. It acts as a vital sensory component, allowing us to see and perceive the world around us.

Damage to the retina, such as in age-related macular degeneration, can lead to vision loss or distortion.
The macula is a small area near the center of the retina responsible for sharp, central vision.
The retina is the innermost layer of the eye that contains photoreceptor cells responsible for detecting light and initiating visual signals.
Light-sensitive cells in the retina, known as rods and cones, convert light energy into electrical signals that are transmitted to the brain via the optic nerve.
The lens of the eye focuses light onto the retina, enabling clear vision.
