Shifting Between Reading And Far Vision Through Using
Lasik To Induce And Create Monovision
_Many people are having Lasik and other surgery to their eyes. This has been creating the result of better vision for the majority, but many people regardless still get hit with a sudden bout of presbyopia, the inability to see close objects clearly when reading.
This can and does occur after the eyes have been treated and successfully corrected with Lasik. It is quite common to be a symptom of a person naturally ageing and unrelated to the previous surgery success.
This can be corrected by wearing, again, the old reading glasses. This is a difficult problem to cure, even with the miraculous science of Lasik vision correction.
One tactic developed is to deliberately induce in the patient the phenomenon called Monovision. This is the idea to target the Lasik Surgery so that one eye is purposely created to be myopic, that is nearsighted and can be used well for reading.
The other eye is either left alone, or surgically changed with Lasik or other treatments to become hyperopic, that is far-sighted, so it can be used for walking around, driving and other more long distance vision tasks.
A certain amount of nearsightedness can be induced in the non-dominant eye by a number of methods. The dominant eye is not usually needed to be corrected, since it is providing the best vision on all distance levels.
The only problem this leaves, using Monovision, is for certain tasks like driving , or if you want to, for example, paint a picture, it is important to have a certain level of depth perception.
This is normally obtained by having the two eyes working together. So patients may end up getting rid of their reading glasses with the procedure to induce Monovision, but still having to get an extra pair of glasses now for obtaining full vision and enhanced depth perception.
Monovision can be achieved in a number of ways:
Regardless of the method used for a person to obtain Monovision, after approximately six to eight weeks the brain adjusts for the changes of vision of the two eyes and automatically shifts between the eye for far vision and the eye for near vision.
Amazingly that is how the phenomenon of Monovision works.

Monovision can be achieved in a number of ways:
- The most no intrusive way it can be achieved directly is by using contact lenses.
- It can be achieved with a procedure called NearVision CK, which uses radio waves to change the shape of the cornea and create some near-sightedness in the non-dominant eye. This effect diminishes over time but can last for years.
- Lasik can also be used to create Monovision by correcting the dominant eye with wave-front guided Lasik, and the other eye with conventional Lasik, that is conventional laser ablation, which aims to leave it slightly nearsighted result.
Regardless of the method used for a person to obtain Monovision, after approximately six to eight weeks the brain adjusts for the changes of vision of the two eyes and automatically shifts between the eye for far vision and the eye for near vision.
