What is Monovision?
Monovision corrects one eye mainly for distance and the other mainly for near, so with both eyes open the brain uses whichever eye suits the task. It can reduce your dependence on reading glasses after 40, when near focusing naturally declines. Many people adapt within days, but some notice reduced depth perception, night-driving difficulty, or a sense of imbalance, and a few never adjust. Because it's a big commitment when done surgically, a contact-lens trial first is the best way to test it.

Monovision is a strategy that addresses the problem of presbyopia, in which people over the age of 40 begin to lose their ability to read or see up close. Monovision is a technique that involves correcting one eye for distance, and the other eye for near vision. When both eyes are open, the brain learns to use the distance focused eye for distance viewing and the near focused eye for near viewing. Many people get used to monovision right away. Others feel a little imbalanced at first, but get used to it within a matter of days or weeks. In some cases, reading glasses may be necessary for reading fine print or viewing very small objects. A small percentage of people cannot make the adjustment to monovision and are better off not choosing this approach. Your doctor will perform a series of simple tests to determine if you are a good candidate for monovision correction. Monovision is available in a variety of methods. The most common approaches include contact lenses, refractive procedures such as LASIK, Conductive Keratoplasty, and Cataract Surgery. Learn more about monovision correction and discover which option is best for you.
