Vision Monocular

Monocular vision

Monocular vision is vision in which a person uses only one eye to perceive the world around him.

With monocular vision, there is no binocular vision, which allows you to create a three-dimensional stereoscopic image due to the slight difference in the images received by the left and right eyes.

Monocular vision can be congenital, with amblyopia (“lazy eye”), or develop with injuries and diseases leading to loss of vision in one eye.

With monocular vision, visual acuity and depth perception of space are reduced. A person estimates the distance to objects and their relative positions worse. This may make it difficult to perform some tasks that require precise hand-eye coordination.

To compensate for impaired monocular vision, special optical devices, depth vision training, and more active use of other sensory systems can be used. Complete restoration of binocular vision during prolonged monocular vision is difficult.



Monocular vision is a visual function that provides an idea of ​​an object in the direct field of vision with a monocular gaze.

The function of monocular vision is preserved in children up to a certain age with different content and coordination of its elements. The quantitative characteristics of the visual function of monocular rectilinear vision are absolute visual acuity, which is determined by the greatest point of clear vision for the isoveram; differentiating ability; relative contrast constant and extinction frequency; maximum efficiency of visual discrimination. They make it possible to objectify neurological defects of the monocular visual analyzer, establish the degree of functional integrity and localization of neurons in the cerebral cortex that carry out eye movement and the function of the visual field.

In children from 2 to 3 years old this is no more than 30°. After 5 years, most children have a visual angle within 50°. The same persists by the age of 6. In adults, the normal field of vision is limited to 15-25° on each side. Involutional processes lead to various defects and disorders of visual functions. Often changes in visual fields are not only symmetrical in nature, but are also combined with



Monocular vision - (v. monoocularis) is a special method of visual perception, through which a person uses only one eye to obtain images of objects and their location in space. However, this defect can be overcome with the help of special optical devices. So, thanks to an ophthalmologist or glasses, you can take off your glasses after a few days. Due to the difficulties of this visual function, children with monoculars show good results when studying in secondary schools; they are more capable than their peers who can see normally with both eyes. But this does not mean that this defect can be alleviated on your own without additional help from doctors.
