What Is Laser Blended Vision & Monovision? Cons & Pros

Laser blended vision also known as Monovision (sometimes also called LASIK Monovision), is a laser eye treatment which corrects short-sight in one eye and long sight in the other. It is primarily used to treat presbyopia or other age-related eye conditions which usually affect patients in their middle age. Monovision adjusts each eye in different ways. One eye is adjusted to see mostly at distance, and a little close up, while the other is the opposite, mostly up close and a little at distance.

What Is Laser Blended Vision & Monovision? Cons & Pros

In most cases, the brain then knows to switch back and forth between distance and close-up vision without causing a distraction to the patient. It combines the two images to give much greater depth of vision, and an all-round improvement in visual acuity that means most patients can throw away those infuriating reading glasses.

If you use glasses to read prior to LASIK or you remove your glasses to read, you may need to use glasses for reading after LASIK, because LASIK does not treat the lens inside the eye. However, a Laser Blended Vision procedure may provide you with suitable near and distance vision.
