Patent ID: 7588336

Claim:
An ophthalmic apparatus capable of measuring a plurality of different eye characteristics of an examinee's eye, the apparatus comprising: an intraocular pressure measurement part which measures intraocular pressure of the eye, the intraocular pressure measurement part including a blowing unit which blows fluid on a cornea of the eye via a nozzle; an optical characteristics measurement part which measures optical characteristics of the eye; a main body in which the intraocular measurement part and the optical characteristics measurement part are provided; a measurement part shifting unit which brings any one of the intraocular measurement part and the optical characteristics measurement part to a measurable state; a working distance detecting unit which optically detects a working distance of the apparatus with respect to the eye at the time of bringing the intraocular pressure measurement part to the measurable state, including a projection optical system for projecting target light onto the cornea, and a photo-receiving optical system for photo-receiving the target light reflected from the cornea; a control part which judges whether it is proper to continue bringing the intraocular pressure measurement part to the measurable state based on a detection result on the working distance, and controls the measurement part shifting unit based on a result of the judgment; and a detection unit which directly or indirectly detects whether or not light photo-received on the photo-receiving optical system is the target light reflected from the cornea, wherein when the detection unit detects that the light photo-received on the photo-receiving optical system is not the target light reflected from the cornea, the control part judges it proper to continue bringing the intraocular pressure measurement part to the measurable state regardless of the detection result on the working distance, and controls the measurement part shifting unit to continue the bringing.
