Abstract Poly methyl metha acrylate (PMMA) is widely in use for eye prostheses and contact lenses. The latter is under ultraviolet radiation of Sun. Therefore the PMMA properties could be influenced and bring the patient to discomfort, because of polymer surface wettability alteration. The latter is under the focus of the present research. Wettability and electron work experiments show similar tendencies, also high correlation has been found between electron work function and absorption minimum area. More interestingly - surface electrical potential depended on exposure under light.
