The maximum distance of distinct vision = 400cm. So the image of the object at infinity is to be formed at 400cm.
Use lens formula
v1−u1=f1
−4001−∞1=f1
P=−0.25D
A person can see clearly object only when they lie between 50 cm to 400 cm from his eyes. In order to increase the maximum distance of distinct…
