Description

Simultaneous vision grading inspection system and method for multi-scene binocular energy stimulation

Technical Field

The invention relates to the technical field of binocular vision function inspection, in particular to a simultaneous vision grading inspection system and method for multi-scene binocular energy stimulation.

Background

Simultaneous vision means that the fovea of the macula and the corresponding retinal component at the periphery of the macula of both eyes have a common visual direction, and both eyes have the ability to look at and perceive simultaneously. The simultaneous vision stores of each person are different, and the simultaneous vision stores are different when watching things in different motion states and different dimensions, and are also influenced by distance factors.

Taking strabismus as an example, the simultaneous vision reserve of an extra-intermittent (external strabismus) patient is insufficient, and the simultaneous vision is likely to be inhibited at one eye when viewing a simultaneous vision still image at a close distance, and cannot be seen at the same time, but when viewing a dynamic image, there is a possibility that the simultaneous vision is present due to higher visual energy stimulus.

When an extra-corporeal patient views the simultaneous vision target image at a long distance, the visual axis may deviate, resulting in inability of both eyes to view simultaneously. In this case, due to the energy level of different perception conditions, the simultaneous vision performance of the extra-and-extra-patient under the dynamic stereoscopic binocular vision condition and the three-dimensional real object binocular vision condition is better than that of the two-dimensional static binocular vision condition.

In the state of naked eyes, the eyes are difficult to distinguish and the condition is met, so that the eyes are difficult to be inspected through naked eyes when the eyes are in different scenes, and no technology is available at present to inspect the condition of the eyes when the eyes are in different scenes.
