Base-In/Base-Out Random Dot Slides

These stereograms have been designed so that one eye sees a picture with a slightly different set of random dots than the picture seen by the other eye. The disparity in the dots causes the pattern to stand out from the random dot background; but only if both eyes are working together.

Cards sets are to be used with the Bernell-O-Scope™ family (BC200, BC200HHTB, BC200HH).

Each set has 8 (Base-In) or 9 (Base-Out) slides of hidden random dot images. Includes cover with instructions for each set and has the hidden shape answer key on the back cover card.

Base-In series has a prismatic effect from 0-14PD
Base-Out series has a prismatic effect from 0-17PD.
