Question

BOOJHO WITH PERFECT EYESIGHT WAS FINDING IT DIFFICULT TO PASS A THREAD THROUGH THE EYE OF THE NEEDLE. WHAT COULD BE THE POSSIBLE REASON?​

Answer 1

He is suffering from hypermetropia or we can say long sightedness.

In this disease, a person can see the far away objects but can't see the nearer objects.

Possible reasons due to which it can be caused are:

• either his lens is too flat
• or his lens length has been shortened
• or both of the above

It can be cured by using a convex lens.

Hope you find it helpful✌
