Better Focus On Aging Eyesight

Prescriptions for progressive lenses differ from bifocals.

Near- and Far-Sighted

Though vision can deteriorate at any age, as adults reach the age of 40, the eye lens stiffens. This hinders the ability to focus at a comfortable reading distance. The blurring, called presbyopia, can occur among people who are nearsighted (myopia) or farsighted (hyperopia).

One solution is to wear low half-oval reading glasses in conjunction with contact lenses for distance. Another solution is to have multiple glasses, each with different prescriptions for distance, intermediate, and reading. More elegant solutions involve multifocal progressive eyeglasses or contact lenses. Progressive contact lenses have one prescription in the central part of the lens and another at the outer regions.
