Distance- and size estimates and stereoacuity judgments were made in the water by divers both with and without a facemask. Without the mask, only stereoacuity was markedly degraded. Distance-estimates were slightly more accurate, despite a great decrease in the range of visibility. Size-estimates were slightly too small. Divers with refractive errors dis not appear to be more handicapped than those with normal vision.
