Question

Explain explain the construction and working of human eye with labelled diagram

Answer 1

Light enters the eye through the cornea (the clear, dome-shaped surface that covers the front of the eye).

From the cornea, the light passes through the pupil. The amount of light passing through is regulated by the iris, or the colored part of your eye.

From there, the light then hits the lens, the transparent structure inside the eye, which focuses light rays onto the retina.

Finally, it reaches the retina, the light-sensitive nerve layer that lines the back of the eye, where the image appears inverted.

The optic nerve carries signals of light, dark, and colors to the area of the brain (the visual cortex), which assembles the signals into images (our vision).
