Abstract
An aspect of the present invention relates to a method of evaluating performance of a film-forming material for forming a functional film on an eyeglass lens substrate or a functional film formed by the use of the film-forming material. The performance to be evaluated is selected from the group consisting of a sliding sensation of a surface of the functional film and an adhesion of the functional film, and the evaluation is conducted based on a change over time in a quantity of photoelectrons generated by irradiating with an X-ray the film-forming material or the functional film.
