Question : The far point of a myopic eye is 60 cm find the focal length of lens to correct

Answer :

But he /she is able to focus properly up to 60cm. the way of correcting this will be to create a virtual image of distant objects (more than 60cm) at 60 cm from the eye. Let us take an object very far from the eye. Hence, u = -infinity.
