In China, for various reasons, many children amblyopia amblyopia due to delayed medical treatment for the best time, resulting in a large number of adult patients with amblyopia. There are great difficulties for their life and work. We design a training software based on visual spatial interactions so as to achieve the aim of improving the contrast sensitivity and visual acuity of adult amblyope. The software's primary modules based on matlab and the corresponding programming tools. In the training process in order to adjust the parameters and automatic input the parameters, text data format used to exchange data with the program. Through the clinical practice, it is showed that the software has a good stability. We analyze the amblyopia patients who use the software for one month, found that contrast sensitivity and visual acuity has a corresponding improvement in the level. It is showed that the software for the treatment of adults with amblyopia at this stage is significant.
