How to tell if binocular vision is normal

In daily life, if we want to look at objects at different distances, we need to adjust and disperse. In fact, this is all about binocular vision, so a binocular vision test should be performed after the refractive examination, and if the binocular vision function is found to be impaired during the examination, a corresponding visual function training plan can be formulated.

Through naked-eye 3D vision training, the eyes are exercised, the "physique" of the eyes is enhanced, and the binocular vision function is improved. By looking at multi-frequency dynamic three-dimensional images, you can see far and near, and exercise eye muscles such as ciliary muscle, lens, rectus muscle, and oblique muscle. Through binocular split-vision and brain fusion, the visual functions such as simultaneous, stereoscopic vision, and fusion vision are exercised.

Improve accommodative hysteresis, improve visual function, all-round eye movement makes the eyes healthier, and improves the visual nervous system and visual imaging quality.

1. What is binocular vision?

The two eyes of the human being are not simply monocular visual superposition, but a complex work based on binocular accommodative function and motor function in order to provide a good stereoscopic visual experience. The examination of ocular accommodation and motor function is a binocular visual function test, including NRA, PRA, BCC, dispersion force measurement and other tests.

2. The importance of visual function.

What are the criteria for good eyes? Many people often think that my normal vision can be achieved, and even that my eyes are very good. Is that really the case?

In order to achieve a good state in the true sense, the human eye must be able to achieve clear and comfortable vision, and at the same time ensure that the eyes have the functions of binocular vision, simultaneous vision and stereoscopic vision, and the eye position is correct, the eyes are balanced, there is no astigmatism, no strabismus, no amblyopia, no heterophoria, and the human eye can achieve long-lasting clarity and normality in the visual behavior. Emmetropia is beautiful, but there is no such thing as emmetropia in theory and in fact.

3. The role of binocular visual function examination.

For adolescents and children with myopia, binocular vision function examination can better make a decision on the development prospect of myopia, so as to propose more effective intervention programs. After a comprehensive "binocular vision function examination" for adolescent myopia patients, a variety of different correction programs can be selected, including spherical lenses, aspherical lenses, anti-fatigue lenses, progressive lenses, and binocular vision function training, etc., to solve the problem of adolescents due to abnormal binocular vision function caused by the rapid deepening of myopia, diplopia, etc., which is divided into adjustment abnormalities, abnormal binocular vision, etc., which can be trained according to the results. For adults, it can be reasonably corrected, reasonably worn glasses, and reasonably trained according to the examination results, which can effectively solve the visual fatigue, eye soreness, eye swelling, nearsight difficulty, and drowsiness caused by abnormal binocular vision function in adults.

4. Binocular vision function test items.

Binocular vision is the basis of binocular vision, and tests include:

1. Motor function (gathering ability) of the eyeball

2. The adjustment ability of the eye, that is, whether one eye can see objects clearly.

3. The coordination ability of the eyes, that is, whether the movement and adjustment of the two eyes are matched.

Only with normal binocular vision can you enjoy comfortable, long-lasting vision.
