Monovision offers an opportunity to decrease your dependence on near vision spectacles
In this situation, one eye is fully corrected for distance vision and the other eye is corrected for reading.
It is worthwhile noting that the eye corrected for near vision will be blurred in the distance, but the two eyes working together compensate this slight compromise to your vision. Not everyone is suitable for monovision correction.
Monovision has been shown to have a small effect on driving performance, with regards to depth perception.
We recommend a trial with contact lenses to simulate monovision prior to surgery to assess how you cope visually with your day-to-day activities and driving.
The strength of the correction of the near vision eye is specifically chosen to suit your needs. For example, some people may wish to keep reasonable distance vision in the near eye and have only limited near focus for situations such as reading a menu at a restaurant or grocery shopping without the need for near spectacles.
These people would still require near spectacles for general prolonged reading or fine print. Alternatively, some people may wish to be capable of reading very fine print. Your visual tasks and general lifestyle are very important in determining the monovision strength.
