Explain the constructions and working of human eye
Answers
Explanation:
Construction of Eye
Construction of EyeIt is through the cornea that the light coming from objects enters the eyes. Just behind the cornea is the iris which is also called coloured diaphragm. A hole in the middle of the iris is called the pupil. Then behind it is the eye lens which is a convex lens.
When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals. These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.

The lens focuses light through the vitreous humor, a clear gel-like substance that fills the back of the eye and supports the retina. The retina receives the image that the cornea focuses through the eye's internal lens and transforms this image into electrical impulses that are carried by the optic nerve to the brain.
