Question

why is a normal eye not able to see clearly the object placed

Answer 1

Hey mate here is your answer

This happens because the ciliary muscles of eyes are unable to contract beyond a certain limit. If the object is placed at a distance less than 25cm from the eye, then the object appears blurred because light rays coming from the object meet beyond the retina.

Hope it helps if you are satisfies then plz mark as brainliest ....

Answer 2

Because the focal length of Normal eye is 25cm.

When any object placed closer than 25cm then the image is FORMED behind the retina. Then object seem blurred.
