Hint: This is the deepest layer, which contains the poles and cone cells, which are referred to as photoreceptors because they are sensitive to light. Cones are photoreceptor cells in the retina that are sensitive to shading. Cones are nerve cells that are more sensitive to bright light. They aid in fine-tuning focal and shading vision.

Complete step by step answer:
The retina houses the light-sensing cells (photoreceptors) as well as the veins that nourish them. The macula, a small region of the retina with many firmly pressed photoreceptors, is the most sensitive part of the retina (called cones). Every photoreceptor is linked to a nerve fibre. The photoreceptor nerve strands are packaged together to form the optic nerve. The optic circle, or the first segment of the optic nerve, is located at the back of the eye.
The photoreceptors in the retina transform the image into electrical signals, which the optic nerve transmits to the brain.
Cones and poles are the two basic types of photoreceptors.
Sharp, point-by-point focal vision and shading vision are also possible with cones.
Poles are prone to night vision as well as fringe (side) vision.
The retina is the eyeball's deepest layer. It is the eye's light-sensitive layer, and it functions similarly to a camera's film in creating an image. Three layers of nerve cells make up the majority of the structure. They're Ganglion cells, and they're the ones closest to the glassy body.
Bipolar cells: Bipolar cells receive synaptic input from either rods or cones or both rods and cones, but they are typically classified as pole bipolar or cone bipolar cells.
In a nutshell, photoreceptor cells are the cells that detect light. Photoreceptor cells, which are made up of bars and cones, are the essential light-sensitive layer. The image is converted into neural motivations, which are then transmitted to the mind for visual discernment.

Note:
Photoreceptor proteins are light-sensitive proteins that detect and respond to light in a variety of life forms. Rhodopsin in photoreceptor cells of vertebrate retina, phytochrome in plants, and bacteriorhodopsin and bacteriophytochromes in certain microbes are a few examples.
