Answer 1

$\huge{\mathcal{\underline{\red{AnSWer}}}}$

We cannot see clearly an object that is too close to the eye. The eye has a limited ability to change its focus. If an object is closer than the eye can focus, it will be out of focus and unclear

Answer 2

Explanation:

If an object is placed very close to the eyes the light reflected from it does not fall on the retina. It either falls in front of the retina or behind it or on the blindspot. Hence, we cannot see the object. The minimum distance for seeing an object clearly is 25cm.
