Sherman Red/Green Playing Cards

These vision therapy cards are a bridge-deck size, but are specially designed for the use with red/green anaglyph filters. The cards make fusion therapy for the amblyopes, strabismics and suppressors fun instead of exercise. The red suit cares are printed in the normal manner with the red numbers, letters and symbols in white. The black cards are entirely overprinted in red. Can be used with patients of all ages.
