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 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.
