Patent abstract
A pupil measuring device includes a portion that is positioned adjacent to a subject's eye and which includes a plurality of concentric circles on a lens as well as an opaque film that moves to cover the circles. Each circle is marked and the film is aligned with the subject's pupil to be circumjacent thereto. The diameter of the pupil can then be read manually or using electronic circuits with the opaque film being used as the indicator of the measurement.
