We can not clearly see an object kept at a distance less than 25cm from eye.

Answer 1

because our eye have specific term too see things it,s range is not too much good so it not see clearly

Answer 2

1. The minimum distance at which an object is placed from the normal eye so that it can be seen clearly without giving any strain on the eye is called as the distance of the distinct vision.

2. This distance is 25 cm for a normal human eye.

3. If the object is placed at a distance less than 25 cm , ciliary muscles is unable to adjust the lens there is a strain on the eye and it cannot be seen clearly.

4. Hence, an object should be placed at 25 cm or more to have a clear and sharp image on it on the retina.
