If you train as many patients as possible both beforehand and afterwards, my experience suggests that you'll have a much lower number of failures and much greater number of successful outcomes.".

(A detailed summary of those trials and their results can be found on the Web at revitalvision.com.) What are the side effects of monovision with contact lenses?

With monovision, you can wear one contact in your non-dominant eye to correct your up-close vision. The brain switches between the eyes as a person's gaze shifts. 6. During the adjustment period, you may experience difficulties such as reading from a distance, or nighttime driving, and you may notice a delay in focusing from near objects to distant objects, but thankfully these side effects pass quickly. But does it help? Axons and dendrites can grow and retract in the retina and the brain; synapses can be lost or gained.

This provides clear, glasses-free vision for most activities. Monovision correction is such an amazing option because, after a period of time, your brain will actually rewire itself to automatically select the appropriate image for the appropriate distance.
