1. 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 photochromic agent sufficient to change to a detectable color upon exposure to predetermined amounts of UV radiation, wherein said device is semi-permanent being disposable and removable without harm to said body part and said device comprises an elastomeric band or non-elastomeric transparent adherent film.

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.

6. 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 nail polish comprising an amount of photochromic agent sufficient to change to a detectable color upon exposure to a predetermined amount of UV radiation, wherein said composition is semi-permanent, being removable without harm to said body part, and wherein said composition further comprises an adherent plastic or petrolatum.

7. A device for detecting a predetermined amount of UV radiation to which a body part is exposed and placing on said body part comprising:
an adherent substrate and a photochromic agent sufficient to change to a detectable color upon exposure to predetermined amounts of UV radiation, comprising said photochromic agent at a plurality of concentrations in different areas resulting in color changes at different levels of exposure to UV radiation, wherein said device is designed to removably adhere to said body part, said device does not result in untanned portions of the skin, being substantially transparent or of sufficiently small dimension, and said device is disposable. - View Dependent Claims (8, 9, 10, 11, 12, 13)
