StereoAcuityTest is a prototype for the diagnosis of amblyopia. This app is based on clinical test for Randot stereoacuity. The left eye sees one set of dots and the right eye sees a second set of dots. The dots are identical except for the dots within the shape that have been horizontally displaced. Amblyotic people may not be able to recognize the images. You need a Google cardboard to try this test.
