Since most cases of poor vision are caused by deformities in the eyeball’s shape, Mohsen Shahinpoor of the University of New Mexico, developed a technique that wraps a thin band of artificial muscles around the eyeball to squeeze it into place. The artificial muscles are made up of polymer strings with gold wires wound around them. Electricity is induced from a power source located behind the ear a person can direct the band to either expand or contract.

Compared with laser surgery, having the equivalent of a rubber band strapped around your eyeball may seem drastic. But Shahinpoor points out that the band could let people adjust their focus on both near and far objects. And unlike laser surgery, the procedure would be reversible.
