monovision

(mon-ō-vi'shun),

monovision

(mŏn′ō-vĭzh″un) [Gr. monos, single, + L. visio, fr. vidēre, to see]
A treatment for presbyopia in which the dominant eye is corrected to improve distance vision and the other eye is corrected for near and intermediate tasks. Standard lenses, contact lenses, or refractive surgery may be used for the corrections.

monovision

Term referring to a method of correcting presbyopia by using a contact lens corrected for distance in one eye (usually the dominant one) and a contact lens corrected for near in the other eye. Binocular vision is impaired with this method, especially stereoscopic vision; however, it has been found to be relatively successful in many cases. It is assumed that at any time one eye is focused while the other is not and the cortical visual system suppresses this latter image (at least the central part of the image). Monovision may also occur without correction in a presbyopic patient who has emmetropia in one eye and myopia in the other eye.
modified monovision is a method of achieving monovision using bifocal contact lenses in which the powers, lens fit or other lens parameters are modified to emphasize distance vision for one eye and near vision for the other eye, while still retaining a reasonable level of binocular vision.

Monovision correction with glasses or contact lenses is another effective treatment to correct diplopia in adult patients with acquired small angle of strabismus (10[DELTA] or less).
Pseudophakic Monovision: A Clinical Guide (online access included)
The 2016 European Society of Cataract and Refractive Surgery Clinical Survey revealed that 43 % of cataract procedures are targeted for monovision. [1] The 'ideal' intraocular lens (IOL) should restore the patients' vision without difficulties or visual negotiations at all distances.
Additionally, it is the only available LASIK platform indicated for monovision LASIK in presbyopic myopic patients.
Several surgical techniques have been developed for the correction of pseudophakic presbyopia, including monovision, (21,22) multifocal IOLs, (6) accomodative IOLs, (23) toric multifocal IOLs, (24) and trifocal IOLs.
In addition, wearing an eye patch causes much inconvenience for patients with monovision, especially in outpatient surgery, after which the patient leaves the hospital immediately.
One way to function with presbyopia without the need for reading glasses is to wear contact lenses that create monovision, in which one lens allows you to see things up close and the other allows for distance vision.
Contact lenses are an option, too, either with monovision, in which a contact lens for distance vision is placed in one eye and a lens for close work in the other, or with multifocal contact lenses, which incorporate the distance and near correction within the same contact lens.
These can be fitted with low-power monovision (one eye far and one eye near), or with low-powered bifocals.
There are two methods to find object position in the z-axis using images: stereovision and monovision. We propose a simple and efficient experimental method to find object distance using an object's area in a single image, and using this distance we find the velocity of a marker along z-axis.
