The day I was able to stretch my convergence to see Circle #4 , I could feel my brain relearn how to control my eyes to relax. I could not stop looking at it because it was so beautiful and felt so good! ( It took many tries for the magic to occur- but I trusted that I would see it eventually and kept trying!) I knew I would be able to continue to make progress then because I was able to access the practice I needed. I have using enjoyed all your Stereo Practice bundles.
