Abstract
A noncontact tonometer has a control circuit which actuates a puffing means to apply an air pulse through a puffing nozzle to the cornea of a subject's eye only when it is found from alignment positional information provided by an XY-alignment detecting circuit that the position of an intraocular pressure measuring unit relative to the cornea is in a predetermined range narrower than and in an allowable alignment range when the alignment of the intraocular pressure measuring unit is readjusted after the measurement of the thickness of a specific section of the cornea.
