There are several studies about the vision stimulation using dichoptic processes, all conclude similarly to an overall improvement in visual acuity and in contrast perception. Each study has its own protocol (duration, tools …).
You can find a summary in the study “Behavioral Training as New Treatment for Adult Amblyopia: A Meta-Analysis and Systematic Review” on the Investigation Ophtalmology and Visual Science journal.

Here are the details of Dichoptic training enables the adult amblyopic brain to learn published by Current biology.
After two weeks, the participants of the 1st group (those who played with a mask on the eye “strong”) have adopted the experience of the second group.
For studies conducted by McGill University in Canada, individuals in both groups experienced an improvement in their visual acuity after the two first weeks. The improvement in acuity for the people in the second group (who played how “dichoptic”) was four times higher.
Similarly, the people of the first group passed to processing on the video game have all seen their performance improve significantly: whether visual acuity, binocular vision and contrast perception.
The study notes that the observed improvements were still present after three months without playing.
The results observed are the following :
