A friend came to ask YOULI. I heard that if you check your binocular vision before wearing glasses, you can wear glasses more accurately. Is this true?

First of all, the two human eyes are not a simple superposition of monocular vision, but a complex work based on the adjustment function and movement function of the eyes in order to provide a good three-dimensional visual experience.

The examination of eye adjustment and motor function is a binocular visual function examination, including NRA, PRA, BCC, reverence force measurement and other examinations. At present, ‘binocular visual function examination’ has become an important part of optometry and prescription glasses.

We know that the result obtained by optometry is the refractive state of the eye at that time. Generally, objects can be seen clearly when the refraction distance is met. In normal life and work, we have to see objects at different distances and need to adjust and converge, that is, the function of binocular vision participate.

Binocular vision function mainly detects the adjustment and convergence functions of both eyes, the fusion function, adjustment abnormalities and eye movement functions of both eyes. Based on the results, reasonable correction, proper wearing of glasses, and reasonable training can effectively alleviate the problems caused by abnormal binocular vision function. The degree of myopia increases rapidly.

Good binocular vision not only allows you to see far clearly, but also allows you to read continuously and comfortably. If there are defects and obstacles in binocular vision, it will cause diplopia, myopically, strabismus, suppression, loss of stereoscopic function, visual fatigue, etc. Therefore, some people with myopia say that wearing glasses makes them prone to feeling dizzy and unable to concentrate. However, binocular vision function examination can accurately identify the problem, analyze the specific conditions of the eyes, and provide symptomatic treatment.
