Based on the latest research results of perceptual learning on adult amblyopia,the paper adopts Gabor as the training stimuli, selects discrimination tasks under the noise environment as the training method, and analyzes and designs the adult amblyopia training system of perceptual learning. The system contains two stimulating tasks in relation to perceptual learning training with adult amblyopia in different conditions, and adjusts the next training model parameter based on the previous training results, which reduces the amblyopia's contrast threshold and improves their visual contrast sensitivity. Given full consideration to the inconvenience of the medical treatment of the longterm patients, the system provides the structure with web support, and synchronizes the training data to the central database. In this way, the system can garantee the parameters for computing the next model's training parameters, and render patients a homebased treatment.
