Answer:
Because eyeglasses often aren't a good solution for the correction of being nearsighted in one eye and farsighted in the other, contact lenses typically are the treatment of choice.

Shortsightedness is corrected using a concave (curved inwards) lens which is placed in front of a myopic eye, moving the image back to the retina and making it clearer. Longsightedness is corrected using a convex (outward facing) lens.
A convex lens (plus lens) is like two prisms placed base to base. Light passing through a convex lens is converged. Convex lenses are used to treat presbyopia, hypermetropia and aphakia.
and having both of the problems in one person eyes is kind of not possible..invalid qns
