Detailed Description

The invention will be further described with reference to the following specific embodiments and the accompanying drawings.

As shown in fig. 2 to 9, a binocular vision training apparatus includes a slanted barrier 400 and a side plate 500. The training instrument is a further improvement of the oblique clapboard type binocular vision training instrument disclosed in the Chinese patent with the application number of 2016213272259, so that the position of an object image can be changed after reflection, the limitation of the existing oblique clapboard type binocular vision training instrument is avoided, and the training effect is better.

Specifically, a plane mirror mounting opening 1 is formed in the inclined partition plate 400, a plane mirror 300 is mounted in the plane mirror mounting opening 1, and the plane mirror 300 is a rectangular plane mirror in a long strip shape. The inclined partition plates 400 at the front and the rear of the plane mirror 300 are sequentially provided with a row of tapered holes 2 at equal intervals. The inclined partition 400 is symmetrically provided with telescopic light shading devices 3, and the light shading devices 3 cover the upper part of the plane mirror 300.
