What is the neural tunic of the eye and what is in tunic?

The neural tunic of the eye, also known as the retina, is the innermost layer that contains the photoreceptor cells responsible for converting light into neural signals. This tunic includes two main types of photoreceptors: rods, which are sensitive to low light levels and enable night vision, and cones, which are responsible for color vision and function best in bright light. Additionally, the retina houses various supporting cells, blood vessels, and neurons that process visual information before transmitting it to the brain via the optic nerve.
