Monovision

Monovision is a technique to reduce the need for reading glasses or bifocals due to presbyopia. Presbyopia occurs when, as part of the natural aging process, the eye’s crystalline lens loses its ability to bring close objects into clear focus. Monovision can be accomplished with LASIK, contact lenses, and/or cataract surgery.

With monovision, your dominant eye is corrected for distance vision, and your non-dominant eye is corrected for near vision. One eye focuses for distant objects while your other eye becomes the reading eye. Your brain learns to adapt to this and will automatically use your correct eye depending on the location of material in view. Most people who try monovision are able to adjust to it.

Here's a quick way to determine your eye dominance.

1. Extend your arms in front of you with your palms facing away.

2. Bring your hands together, forming a small hole by crossing the thumbs and fore fingers.

3. Choose a small object about 15-20 feet away from you. With both eyes open, focus on the object as you look through the small hole.

4. Close one eye and then the other. When you close one eye, the object will be stationary. When you close the other eye, the object should disappear from the hole or jump to one side.

5. If the object does not move when you cover one eye, then that eye is dominant. The eye that sees the object and does not move is the dominant eye.
