What is Binocular Rivalry? 

Binocular rivalry is a phenomenon of visual perception in which perception alternates between different images presented to each eye. 

From the moment we open our eyes, we receive two slightly dissimilar images of the world. This study is to help us learn how your two eyes see together and  how your brain filters out information that you don’t need to pay attention to in your environment 

If you have not done so already, please download the rivalry app using the steps below. If you have already downloaded the rivalry app, please continue to instructions below titled “Pairing the bluetooth keypad”.

During this experiment there are three possible things you could see on the screen:


a red image, a green image, or a mixed image (an image that is both red and green) like below
