Explanation:
A person who is long sighted can focus clearly on distant objects but cannot focus on near objects. This is because the eyeball is too short. Light from near objects is focussed at a point behind the retina resulting in a blurred image. This defect can be corrected by wearing a convex (converging) spectacle lens.

Answer:
Multifocal contact lenses enable you to see both near and far in each eye. Regular contact lenses also can correct the problem through monovision where one eye has a contact lens with a prescription to see up close and the other eye has a contact lens with a prescription to see far away.
