Answer:
Light gets into your eye through your pupil. The light travels through your pupil to the retina, light-sensitive cells at the back of your eye. Your retina changes the light into a nerve signal. The nerve signal travels along the optic nerve to your brain.
The light then passes through the pupil, a small opening in the centre of the eye. ... As our eyes move from near objects to distant objects, a process known as visual accommodation occurs. Visual accommodation is the process of changing the curvature of the lens to keep the light entering the eye focused on the retina.
Main function. The main function of the eye is to convert light from the outside world into electrical nerve impulses. These impulses then travel to the part of the brain responsible for vision (the visual cortex) where they are interpreted as a visual scene. Hope this helps! :)
