The invention provides an amblyopia treatment system based on the AR (augmented reality) technology. The system comprises an acquiring module, an overlapping module and a rendering module, wherein the acquiring module acquires an object in the scene of the AR (augmented reality) technology, the overlapping module overlaps the preset amblyopia treatment image to the object of the scene of the AR, and the rendering module renders the amblyopia treatment image according to the amblyopia detection result, so that two patterns with the same visual picture in the amblyopia treatment image are presented with different rendering parameters.
