3. How to use this program….
The next slide consists of two hemicircles or red and green.
The patient wears a red-green goggle to dissociate the two eyes, so that only one of a pair is visible with each eye.
The first slide has one set. The subject views it and decides which object is bigger – the red or the green.
If the red object is bigger, clicking the link icon on the red hemicircle brings the appropriate set of slides; if the green object is bigger, clicking the link icon on the green hemicircle brings the appropriate set of slides.
The subject views the four sets in each screen and selects the set in which the red and the green objects appear to be of the same height – tips coincide.
The number mentioned at the lower left part of the object pair is the image size disparity in %
