A device for non-invasive determination of intra-ocular pressure comprising a pressure chamber with a flexible membrane for engaging with the cornea of a subject's eye and a strain gauge, wherein the pressure chamber may be internally pressurised and thereby exerts a pressure via the membrane upon both the cornea and the strain gauge to that result in a deflection of the cornea and strains being generated at the strain gauge, which, in turn, enable to establish a correlation between inter ocular pressure and strains.
