A system for measuring pressure of an eye comprises an excitation source (101) for producing a travelling air vortex ring and for directing the travelling air vortex ring to the eye, a detector (102) for detecting an interaction between the travelling air vortex ring and a surface of the eye, and a processing device (103) for determining an estimate of the pressure of the eye based on the detected interaction between the travelling air vortex ring and the surface of the eye. A useful range of the travelling air vortex ring is significantly longer than a useful range of for example a shock wave. Thus, the excitation source that produces a travelling air vortex ring can be significantly farther from an eye than for example an excitation source that produces a shock wave.
