Monovision may be an option if you need vision correction for both near and far distances. Monovision corrects your dominant eye to see far distances and your nondominant eye to see close-up ones. Your eyes and brain adjust to this correction to see objects clearly, regardless of their distance. You may find that you still need to wear glasses for intermediate vision or when using your close-up vision for a long time.

Most people have a dominant eye one that you prefer to see with if you had to close one eye. With monovision, the vision in your dominant eye is corrected for distance vision, while your other eye is intentionally left somewhat nearsighted to allow you to see close objects. Both eyes still work together, allowing you to see clearly at any distance.
While this way of seeing may sound complicated, many people find they adapt well to this technique. In fact, with both eyes open, they may not be able to tell which eye is set for distance and which is set for near.
However, monovision is not for everyone. With monovision, the eye that sees well for distance vision will be slightly blurred up close and the eye that sees well up close will be slightly blurred when looking at distant objects. But with both eyes open, typically the result is acceptably clear and comfortable vision at all distances.
Therefore, the term "monovision" is somewhat misleading. The two eyes still work together as a team so you can see clearly at all distances; it's just that one eye sees more clearly than the other at a certain distance, and the "stronger eye" will depend on whether you are looking at something far away or up close.
Though monovision might sound difficult to adjust to, most people adapt to it easily and don't even notice which eye is their "distance eye" and which is their "near eye" when both eyes are open. Depending on your daily visual demands and how you respond to monovision with contact lenses, your eye doctor may recommend a variation of monovision to best suit your needs.
These variations include:. Mini-monovision: In this variation, a less-than-typical magnifying power is added to the near vision lens. Mini-monovision often is an excellent solution for people who find that standard monovision does not give them the sharp distance vision they desire, and they don't need to do a lot of close-up work or they don't mind wearing reading glasses on occasion.
Not everybody tolerates it. Monovision can be achieved using contact lenses, artificial lens implants intraocular lenses or through refractive surgery such as LASIK. Establishing eye dominance is easy given studies have found a link between eye dominance and handedness, i. Monovision corrects vision in the dominant eye for distance vision while the other eye is left nearsighted to enable a person to see close objects.
The eyes still work in unison allowing clearer vision at any distance. Monovision works since the brain is more focused on visual information from the dominant eye. Although monovision may appear complicated, most people adapt quickly to this vision correction technique.
