"Retinas" Pronounce,Meaning And Examples

"Retinas" Meaning

The plural form of "retina".

A retina is a layer of tissue at the back of the eye that converts light into electrical signals that are sent to the brain, allowing for vision. Specifically, the retina consists of specialized light-sensitive cells called photoreceptors (rods and cones) that respond to light and transmit signals to the brain through the optic nerve.

In the context of biology and medicine, the retina is a critical part of the visual system, and any damage or disease affecting the retina can lead to vision loss or blindness.
