A dynamic tonometry device includes a probe, a housing, a sleeve, a light source, an image sensor, a pressure sensor, a microprocessor and a display storage. The probe is a truncated cone with small at left and large at right. The sleeve is fitted on the probe. An end face of a small end of the probe is situated to a left of a left end face of the sleeve. A right end of the sleeve is connected to a left end of the housing on a large end of the probe is installed the pressure sensor inside the housing are installed the light source and the image sensor. Light emitted by the light source is collimated into a light beam which is incident to the probe and totally reflected before entering the image sensor. With the microprocessor are connected the pressure sensor, the image sensor and the display storage.
