The present solution relates to a pressure-adjustable test eye for tonometers, in particular for contactless tonometers. The proposed pressure-adjustable test eye for tonometers consists of a base element with a pressure source, at the edge of which base element a film, simulating the cornea, is fastened, the resulting cavity being filled with liquid or gas. According to the invention, the film simulating the cornea has, starting from a central, mechanically excitable region, gradually varying conducting properties for mechanical waves. For simulation of the cornea, a film is used which is self-supporting and has a certain residual stiffness. The pressure-adjustable test eye is intended for tonometers, in particular contactless tonometers, in order to generate the most realistic measurement signals possible, in order to be able to carry out regular function tests and/or calibrations. However, the pressure-adjustable test eye can also be used in elastography or elastometry in order, for example, to enable a pre- and postoperative evaluation of corneas to be carried out.
