what is the functi on of pupil
Answers
Answer:
The pupil is essentially a hole in the center of your iris that controls how much light enters the eye. It's size is controlled by the relaxing and contracting of the iris. When there is high light intensity, the pupil shrinks while it grows in low light intensity. This is to ensure there is enough light for vision without damaging the sensitive retina.
So, in order of how we see, here are their roles.
1) Light passes through the cornea covering the eye which refracts it.
2) The iris regulates the size of the pupil which controls how much light is allowed to enter the eye.
3) Behind the pupil is the lens that focuses light (or an image) onto the retina .
4) The retina contains many photoreceptor cells that convert light into electric signals.
5) These signals are processed further then travel through the optic nerve to be collected and interpreted by the brain.
Explanation:
The function of the pupil is clearly that of controlling the amount of light entering the eye, and hence the light reflex.
