The above person prefers to remove the spectacles while looking at the sky. Explain why?

Text Solution

Verified by Experts

c) A hypermetropic eye may have normal far point i.e., it may have enough converging power to focus parallel rays from infinity on the retina of the shortened eyeball. Wearing spectacles of converging lenses (used for near vision) will amount to more converging power than needed for parallel rayl. Hence the person prefers not to use the spectacles for far objects.
