Abstract
A tonometer is adapted to measure intraocular pressure by applying pressure onto of an eye being examined via its eyelid. The tonometer is provided with a pressure means that presses against the eyelid of a subject eye to thereby apply pressure to the eye. The load applied to the pressure means is detected by a Load sensor and used to calculate intraocular pressure of the eye. The tonometer with this arrangement is structurally simple and compact, operationally safe, and does not cause the patient to feel fear and discomfort.
