The process of forming an image on the retina of the human eye and its subsequent processing by the human brain involves several steps:

1. Image Formation on the Retina:
   - Light entering the eye passes through the cornea, pupil, and lens, which collectively focus the light onto the retina at the back of the eye.
   - The lens adjusts its shape to ensure that the image is properly focused on the retina.
   - The retina contains light-sensitive cells called photoreceptors, specifically rods and cones, which convert the incoming light into electrical signals.

2. Signal Transmission:
