Given a condition in which each eye percieves the same image as slightly larger or smaller than the other in the horizonal or vertical direction - thus making it more difficult to combine the two into a single coherent image - can corrective lenses be used to adjust the images so that they both appear the same size?

1Is this purely hypothetical, or do you believe that this condition actually occurs? On physical grounds, this doesn't seem possible. The size of the image on the retina is given by the product DA, where D is the diameter of the eyeball and A is the angular size of the object in radians. (This assumes that it's in focus on the retina. If it's not in focus, you would presumably wear glasses to correct for that.) Even if the size of the image were somehow wrong (e.g., if the eyeball changed size), your eye-brain system is probably plastic enough to adapt over time. – Jun 19 '20 at 17:56
