Regarding the human eye, consider the following statements: 1. Light ...
- Light enters the eye, through a thin membrane called cornea. Cornea forms a transparent bulge on the front surface of the eyeball.
- Pupil is a pigmented layer of tissues that makes up the colored portion of the eye. Its primary function is to control the amount of light entering in the eye.
- The eye lens forms an inverted real image of the object on the retina. The retina is a delicate membrane having an enormous number of light-sensitive cells.

Regarding the human eye, consider the following statements: 1. Light ...
Cornea and Pupil:
- Statement 1 is correct because light enters the eye through the cornea, which is the transparent outer covering of the eye.
- Statement 2 is also correct as the pupil, located in the center of the iris, controls the amount of light entering the eye by adjusting its size.
Retina and Image Formation:
- Statement 3 is true as well. The lens of the eye focuses the light onto the retina, which contains cells that convert the light into electrical signals. These signals are then sent to the brain through the optic nerve.
- The image formed on the retina is indeed inverted due to the way light rays are refracted by the cornea and lens before reaching the retina.
Conclusion:
- Therefore, all three statements are accurate when it comes to the functioning of the human eye. The cornea allows light to enter, the pupil regulates the amount of light, and an inverted real image is formed on the retina for further processing by the brain.
