What is the innermost layer of tissue in the eye called?

The innermost layer of tissue in the eye is known as the retina. It plays a crucial role in vision by converting light into neural signals which are then sent to the brain for interpretation. The retina contains photoreceptor cells (rods and cones) that are responsible for sensing light and color, making it essential for visual perception.

In contrast, the cornea is the transparent front layer of the eye that helps to focus light, but it is not the innermost layer. The sclera is the white outer coat of the eyeball, providing structure and protection, but again, it is not the innermost layer. The iris, which is the colored part of the eye, regulates the amount of light that enters through the pupil but does not serve as a tissue layer. Each of these components has distinct functional roles in vision, but the retina’s unique ability to transduce light signals makes it the innermost layer crucial for the process of sight.
