Abstract
Diyne monomers are used as photochromic agents in devices or formulations. The devices and formulations may be applied to body parts for semi-pemanent attachment at various sites to allow for detection of levels of ultraviolet radiation. Clear films may be placed on eyeglass lenses to detect UV radiation occurring between the lens and the eye.
Claims21
A method of detecting a preselected amount of UV radiation in association with a body part, said method comprising:
- placing on said body part a device or composition comprising an amount of a diyne monomer as a photochromic agent sufficient to change to a detectable color upon exposure to a predetermined amount of UV radiation, wherein said device or composition is semi-permanent being removable without harm to said body part and said device comprises an elastomeric band or non-elastomeric transparent adherent film and said composition comprises an adherent plastic or petrolatum incorporating said photochromic agent.
A method of detecting a plurality of different amounts of UV radiation in association with a body part, said method comprising:
- placing on said body part a device comprising areas having differing amounts of a diyne monomer as a photochromic agent sufficient to change to a detectable color upon exposure to predetermined amounts of UV radiation, wherein said device is semi-permanent being removable without harm to said body part and said device comprises an elastomeric band or non-elastomeric transparent adherent film.
A device for detecting a predetermined amount of UV radiation and designed for wearing on a body part comprising an elastomeric composition and a diyne monomer as a photochromic agent sufficient to change to a detectable color upon exposure to predetermined amounts of UV radiation.
A device for detecting a predetermined amount of UV radiation and placing on a body part comprising an adherent substrate and a diyne monomer as a photochromic agent sufficient to change to a detectable color upon exposure to predetermined amounts of UV radiation.
An eyeglass lens to which is adhered a clear film comprising a diyneoic acid monomer as a photochromic agent sufficient to change to a detectable color upon exposure to predetermined amounts of UV radiation.
