Question

formula for focal length of concave used to recify myopiahi​

Answer 1

Answer:

Of course, the lens will be a concave one (read the intuitive explanation for the reason behind using a concave lens for a myopic eye). and v= -F [obviously, the image distance should be F because the person can't see beyond F]. Thus, the focal length of the concave lens is equal to the far point of the myopic eye.✌️✌️
