Question
Which of the following options indicates the function of the part of the human eye shown below?
- Controls the amount of light entering the eye
- Helps the eye lens adjust its focal length
- Protects the eye from external injuries
- Focuses the light rays entering the eyes onto the retina
Hint:
It is biconvex and transparent.
The correct answer is: Focuses the light rays entering the eyes onto the retina
The correct option is d)Focuses the light rays entering the eyes onto the retina.
Light passes through the lens (the transparent part of the eye). The lens works with the cornea to correctly focus light onto the retina.
When light hits the retina (the light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors convert the light into electrical signals.
