What is the innermost layer of tissue in the eye, containing photoreceptors?

The innermost layer of tissue in the eye that contains photoreceptors is the retina. The retina is a crucial component of the visual system, as it contains two main types of photoreceptors: rods and cones. Rods are responsible for vision in low light conditions and do not detect color, while cones are responsible for color vision and function best in bright light. The retina transforms light into neural signals, which are then transmitted to the brain for image processing.

This layer is vital for the perception of visual stimuli, and its health is essential for maintaining good vision. Other structures in the eye, such as the cornea, lens, and iris, play important roles in focusing light and regulating how much light enters the eye, but they do not contain photoreceptors and are not involved in the initial processing of visual information.
