Various kinds of aerosols such as a mixture of hairspray resin and its solvents, a perfume, a soap water, and ask in-lotion were sprayed onto the contact lens which was mounted on the eye-model made of wood, varying the parameters as the distance between nozzle and contact lens and the spraying time duration. In the case of both the hairspray and the perfume including an ethanol as solvents, the shape of contact lenses has changed tremendously Jess than 1 minute after the exposure to the aerosol particles and then it continued until the lens surfaces were completely flipped over. Driving force for the lens distortion seems to be the expansion coefficient difference between the inner and outer surface of lens, which was caused by the heat of vaporization of ethanol included in the aerosol and subsequent temperature decrease induced on the lens surface.
