Abstract Poly methyl metha acrylate (PMMA) is widely used for eye prostheses and contact lenses. These devices are worn outdoors and, therefore, exposed to the ultraviolet radiation of Sun. This may cause changes in PMMA properties and bring discomfort to the patient, for instance, because of polymer surface wettability alteration. Namely, alteration of wettability of PMMA due to ultraviolet radiation and correlation of wettability with other surface properties is under the focus of the present research. Wettability of PMMA changes due to UV irradiation in irregular manner. Besides, good correlation existed between wettability, electron work function and peculiarities of the absorption spectra of PMMA
