Monovision

Monovision is a treatment in which one eye is fitted with a lens for seeing things at a distance and the other eye is fitted for seeing close-up. After a period of adjustment, the brain switches to the eye which is giving the clearest image at the time. Typically, monovision has a higher success rate than bifocal lenses. While monovision is successfully used by many people, others find adapting difficult. Mildly blurred vision, dizziness, headaches and a feeling of slight imbalance may last for a few minutes or for several weeks as you adapt. Generally, the longer these symptoms last, the more unlikely it is that you will adapt successfully.

Adjusting to demanding conditions

Eye care practitioners urge people new to monovision to avoid visually demanding situations at first, and instead to wear their new lenses only in familiar situations. For example, it may be better to be a passenger, rather than a driver, in a car. In fact, you should only drive with monovision correction if you can pass your driver's license eye examination while wearing it.
