A low vision training device

Abstract

The invention provides an amblyopia training instrument. The amblyopia training instrument comprises a display module, a sight tracking module and an image processing module. The display module is used for displaying field-of-view contents and can display the left eye field-of-view content, the right eye field-of-view content and the binocular field-of-view content. The sight tracking module tracks a sight track of a user. The display module displays the binocular field-of-view content including a motion target. The sight tracking module tracks gazing tracks of the left eye and the right eye of the user to the motion target, judges the dominant eye and amblyopic eye according to the approaching degree of the gazing tracks and a real motion track of the motion target and records the binocular gazing tracks. The display module displays the field-of-view contents including the motion target repeatedly for multiple times to the amblyopic eye according to the judging result and records a gazing track that the amblyopic eye gazes the motion target. According to the amblyopia training instrument, the eyesight training scene can be enriched effectively, and the eyesight improvement efficiency is improved.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to an amblyopia training instrument. Background technique [0002] Amblyopia is a common eye disease in children in ophthalmology.
