Light electronic intraocular pressure tracer

The utility model relates to an ophthalmic instrument for measuring and tracing the intraocular pressure of human eyes, comprising a test head, an integrative box, and a shield line for connecting the test head and the integrative box. The test head comprises a movable iron core pressing, a metal outer shell, and an annular coil which is fixed in the outer shell and is sheathed on the iron core pressing. A test circuit, a single chip computer, a nixie display, and a memory are arranged in the integrative box. The test circuit is composed of an LC oscillator, an isolating circuit, an amplifying circuit, and a shaping circuit which are connected. An oscillating coil and a coupling coil in the oscillator are the annular coil arranged in the test head. The pressing moves to bring on inductance and oscillation frequency to change. By the inductance and the oscillation frequency which are processed by the single chip computer, the utility model searches for intraocular pressure data and displays.
