Monovision Adjustment - An Alternative to Bifocals

What is a monovision adjustment? A monovision adjustment is an alternative for those people who need bifocals. To explain the procedure in very basic terms, surgery is used to adjust the vision in one or both eyes so that the person can see well at a distance in one eye and see better close up in the other. If the near vision is already good, only one eye will undergo surgery.

Who is a candidate for adjusting monovision?

For most people who need corrective lenses or who opt for corrective surgery for vision issues, the problem is that can't see well up close or that they can't see well at a distance. For those over age 40, the issue often becomes that they can't see well at either distance. There are several options at that point, including a monovision adjust that will help the person see things that are near and those at a distance.

How does the monovision adjusting work?

Remember that your eyes are really nothing more than receivers. The brain does the actual processing of the information gathered by the eye. The blurry or fuzzy look often associated with poor vision is a result of the eye not properly gathering the information. But if you close one eye, you can still see the image in front of you. The monovision adjusting surgery is done only on the dominant eye for distance vision. If the person also can't see well close up, surgery is performed on the non-dominant eye for close vision. That means that one eye (helped by the other) focuses in on distant images while the non-dominant eye focuses on the nearer objects. In this way, both are processed in a cleared way and the result is that the person can see better both near and far.

What problems are commonly associated with monovision adjustments?

Remember that if you close one eye, your perception (including depth perception) of the image changes. Those who have undergone monovision adjustments sometimes report problems with depth perception and trouble seeing in dimly lit areas.
