During the period of adjustment, monovision contacts may cause blurred or double vision, nausea, headaches, dizziness and general discomfort. Some people may find that their eyes are easy to get tired when reading. And they may see halos or glare around the lights in the evening.
People who have normal stereo vision may suffer the loss of depth perception which is caused by monovision contacts. So drivers shouldn't wear monovision contacts, especially when they are driving at night. Because it is very dangerous due to the loss of depth perception.
Monovision sometimes leads certain patients to a dilemma that it may bring neither perfect distance vision nor clear close vision. In addition, the two eyes may be not in perfect coordination so that depth perception is affected. Monovision contact lensesâ€™ fitting requires more skills and more time. The wearerâ€™s vision dissatisfaction can be magnified even by a slight change in the lens power, which may also spend several days to adjust.
Yes I had monvision done, not by choice,I hate it giving me bad headache so much, can't drive without glasses at night, like having one high heel shoe on and one flat shoe, horrible, eyes should be the same most of humans are born with same sight distance, very unhappy, with the eye doctor.
