What is Monovision?

Monovision is a way of using one eye to see distance and the other eye for almost vision. Contact lenses, refractive surgery and intraocular lenses are all methods used for monovisions. When a patient chooses a monovision, a dominant eye, or that is used to focus on the camera, it becomes the eye of the distance and the other eye is focused on close vision.

The monovision method works because the brain learns to adapt to which eye sees at which distance. This method is also a form of concept known as simultaneous vision . When adapting to this way of vision, there is usually a set -up period. Most patients find that they are able to adapt. Because surgery is a permanent solution, doctors recommend that patients first try Monovision contact lenses.

The disadvantages of monovision include a lack of visual sharpness. Persons who require a very sharp vision due to a hobby or profession may not be satisfied with the results of the monovision.Another disadvantage of Monovision Jeto that some patients are experiencing a decrease in the perception of depth or blurred vision in the eye that focuses on almost vision in certain situations.

Some patients report problems with the vision of shadows when trying to read a small press. Due to these side effects, it could still be necessary to wear prescription glasses for some activities such as night ride. The advantage of monovision over other options, such as multifocal lenses, is lower costs. Multifocal lenses have separate parts of the lens focused on almost vision and for distance vision.

with the popularity of lasik surgery, which restores the patient's ability to see without glasses, some patients older than 40 years may be forced to give up their ability to see close up to see at a distance. Some choose Monovision as a compromise.

Presbyopia, the inability of the eye to focus on close, medium and distances, occurs withE U for most people around 45 years. This is assumed that this happens because the natural lens of the eye loses its flexibility and the ability to be flexible and concentrate as at a younger age. Presbyopia makes it difficult to read or see at close distances and usually requires reading glasses. Because presbyopia is a continuous condition, the ability to concentrate decreases every few years, usually until a person reaches his half of the 60s.
