While cost varies depending on the patient and the facility, you can expect to pay somewhere between $1,500 and $3,000 per eye. Therefore, if the non-dominant eye is fitted with a near-vision contact lens, our distance vision will not get affected much. That's the premise behind using Gabor patches to trigger perceptual learning. In most patients, the brain adapts to monovision easily. We are the only center in the country allowing you to ask our doctor a question, and he will answer personally. With monovision correction, the non-dominant eye is adjusted depending on whether or not you were far or near-sighted. This leads to difficulty in reading and focusing on near objects. "Adaptation can happen quickly, as when we adapt to light or dark, but some types of adaptation happen very slowly over weeks or months," notes Martin A.

It is suitable for driving and most of your other . You may still need reading glasses, but farther away objects are in sharper focus.

The best way to do this is by telling a story that is unique. Rather than using contacts, your eye doctor can make monovision adjustments using LASIK eye surgery adjusting one eye to see distance clearly and the other to see better close-up. You can either focus on the screen door, or on the image beyond the screen. . But your reading prescription is different depending on where you want to focus. Monovision cataract surgery replaces the natural lens with an intraocular lens (IOL) that corrects for distance vision in one eye and for near vision in the other eye.

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. I have a "close up" eye and a "far away" eye and crap depth perception! It's a standard contact lens, but rather than make both eyes see well far away, one eye is set to see up close instead.
