Abstract: The present invention is a device to enable a physician to accurately measure masses encountered during rectal, pelvic, surgical or other internal examinations where the examiner cannot see the objects but must judge their size by only palpitation. The device comprises a one-piece tight fitting glove of thin elastic impervious material with four fingers and a thumb with palpable markings located on one or more fingers of the glove. The markings are spaced at intervals of known length between the interphalangeal joint and the tips of one or more fingers on the pad or palm side, and can be felt on the inside of the glove such that the physician can accurately measure masses which he or she is able to feel but cannot observe.

Abstract: The present invention is an improvement over existing methods of testing a patient for color perception. The present invention provides a means by which color perception can be tested at the same time that visual acuity is measured. The eye chart with color vision screening comprises a chart which displays objects of progressively smaller sizes with the larger sized objects being displayed in color in order that color perception can be measured and with the smaller objects displayed black on the white background in order that the chart's effectiveness as a tool for measuring visual acuity is not reduced.
