stereo blocks in the Play Store has a calibration for strabismus:
"Also since many people with lazy eye also have misaligned eyes (strabismus) there is an offset calibration that can be used to compensate for this. Due to the size of the device screen there is a limit to how much of a misalignment the game can correct for."
Basically you apply the offset that fits your degree of eye turn and as you play longer, you align the blocks to fall closer to what normal eye alignment would be.
Its free, all you need are red and blue glasses:

BTW this basically works similarly to a Fresnel Prism. Here is a story here for reference:
"In order to maximize this development I do a series of vision therapy exercises that strengthen the connectivity between my brain and my right eye. Every so often, I then lessen the power of that new lens. That lens is called a fresnel prism and it bends rays of light in different directions (in, out, up or down) so as to re-align objects of regard with the most sensitive part of each eye (the fovea) and make single binocular vision possible in the presence of non-aligned strabismic eyes. In short, it adjusts my eye straight, and as you can see in the photo link, I started out with an extremely powerful lens and am now nearing zero. Soon I will not need prisms at all and my eye will be straight on its own."
I bought my red/cyan 3D glasses couple of weeks back and installed these two (Stereo Blocks, Stereo Balls) games on my android phone and then last week while I was looking for other alternatives online I found this site which says: > no studies have shown that 3d anaglyph can be used to encourage binocular vision and treat amblyopia.
I am confused which method should I use?
