In contrast, the technique of modified monovision or blended vision produces a predictable result with a high . Monovision is a method of distance vision correction to account for presbyopia. With both eyes open, your brain blends the distances together so that you can see both far and near. Therefore, if the non-dominant eye is fitted with a near-vision contact lens, our distance vision will not get affected much. Do that, and before you know it, there wont be a noticeable disparity anymore as your eyes and mind will have adjusted accordingly.

The revised program provides more of whatever specific stimuli led to improved vision and better responses. (A detailed summary of those trials and their results can be found on the Web at revitalvision.com.)

Monovision reduces or eliminates the need for two pairs of glasses by allowing your eyes to adjust to both close-up and distance vision with the help of contacts. Some people never adjust, but most do. Another option includes bifocal or multifocal contact lenses. Logically, once a person gets exposed to monovision treatment, his/her eyesight will be affected, since, before, his/her eyes worked in concordance, adjusting together whatever they needed. This amazing feat of neuroplasticity actually allows the patient to achieve relatively normal eye function, without bifocal contacts or glasses. "You don't have to take it on faith that training the brain, at any age, can have a substantial impact on a patient's successful rehabilitation following surgery. The procedure is for Presbyopia, so is really more for personal satisfaction rather than any true defect. 5. What is monovision cataract surgery? One available system designed to enhance adaptation following implantation of multifocal IOLs is an Internet-based program offered by RevitalVision (using technology pioneered by its predecessor, NeuroVision), based in Lawrence, Kan. "Our training system is designed to enhance neuroadaptation by making the visual system analyze information presented using Gabor patches," explains Brendan Sheil, CCO of RevitalVision. Certain professions tend to attract certain types of brains, and that may make them better or worse candidates for interpreting visual cues following surgery. [4] One may also have difficulty with his/her intermediate vision. Till that happens, the person undergoing monovision experiences some loss of depth perception and blurring of vision. They are not a special type of contact. In my experience, most people adapt to monovision in 1-2 weeks, or they wont adapt.

The key is that both your eyes combine their strengths and improve your general vision. What kind of eye surgery does Blended Vision use?

But it also causes the brain to miscalculate the depth of moving . "The brain is incredibly plastic and is constantly changing and redirecting neural networks throughout life. By now of course, the big question in most peoples mind is of course how long? There is a readjustment period following any monovision correction, whether surgical or otherwise. While Monovision is not a perfect solution to presbyopia, for carefully selected patients, it is well tolerated and very satisfactory over 85% of the time. Does it work with everybody?

Many ophthalmologists haven't had to devote too much time to worrying about the neurological half of the visual systemuntil now.

This article provides some information on the same. How long does it take to adjust to blended vision? Furthermore, when you implant a multifocal lens the change they have to adapt to is partly negative; you're degrading their image perception in exchange for multifocality. "We've developed a new way to quantify this by measuring the magnitude of interocular suppression, and we recently published results from the first study of our new approach.4 We suspect that those who turn out to be more ambidextrous, in terms of which eye they're using, will have an easier time neuroadapting to multifocals or monovision.
