Abstract
Abstract A pair of spectacle is provided with one or more bodies or chips of material that respond to ultraviolet radiation to produce different visible effects depending upon the ultraviolet intensity. The bodies are mounted outside the normal field of view of the wearer but within the field of his peripheral vision so that the wearer may constantly monitor his exposure to ultraviolet and determine when it approaches a level to which he is unduly sensitive.
