A meniscus lens is concave on one side and convex on the other.

a) For a contact (meniscus) lens, the inner surface is curved to fit the eye with radius 7.8 mm. The lens with n=1.56 needs to have a focal length of 44.4 cm. What should be the curvature radius of the outer surface?

b) If the person using this lens can now clearly see objects as close as 20 cm, what is this person's near point?
