VISION UNDERWATER
Abstract
Visual resolution of Landolt Ring targets in clear water at short range was found to be better than in air at the same physical distance, when target luminances were equated for the two conditions, but fell below predictions based upon the magnification of underwater targets. This is ascribed to a greater lens fogging problem underwater and the lack of sufficiently small targets for some observers. Both size and distance were overestimated underwater, except for short ranges. Fluorescent paints were found to be more visible underwater than non-fluorescent types.
