One problem that may occur with monovision is hampered visual clarity for both distance and near vision. Some patients with monovision also complain about reduced depth perception, states AllAboutVision.
Monovision is a form of treatment for the medical condition presbyopia, which is commonly associated with the aging process, explains EyeHealthWeb. A contact lens is fitted on the dominant eye to enhance distance vision, while the weak eye is fitted with a contact lens for viewing objects up close. Although both corrected eyes still work in tandem, some people with monovision tend to have problems achieving proper focus.
Monovision may result in blurred near vision, and it may still require further use of reading glasses, notes AllAboutVision. Distance vision is likewise too compromised for some people since only one eye is corrected for looking at distant objects.
