Abstract: A contactless ophthalmotonometer includes a cylinder, a piston movably provided inside the cylinder, an actuator (solenoid) configured to move the piston inside the cylinder by applying current to compress air inside the cylinder, a nozzle configured to spray the air compressed with the piston to a subject eye, and a current application control unit (measurement control unit) configured to apply the current to the actuator, wherein the current application control unit performs first application processing for applying the current of a first current value to the actuator and, when a predetermined switching condition is satisfied while the first application processing is being performed, the first application processing is switched to second application processing for applying the current of a second current value higher than the first current value to the actuator.
