Verified step by step guidance

Begin by understanding the anatomy of the eye and the path that light takes as it enters the eye.

Light first passes through the cornea, which is the transparent front part of the eye that helps to focus incoming light.

After the cornea, light travels through the aqueous humor and reaches the iris, which controls the size of the pupil and thus the amount of light entering the eye.

The light then passes through the lens, which further focuses the light onto the retina by adjusting its shape.

Finally, the light reaches the retina, which is the light-sensitive layer at the back of the eye where photoreceptor cells convert light into neural signals for the brain to interpret as visual images.
