Our eBay Store About Us Contact/Follow Us FAQ Zeiss Humphrey Lensometer 350 Reference Eye Accessory Kit NIB $196.12 Condition: Product Details This accessory kit contains a reference eye, a test piece simulating a human eye, for use with 350 model Zeiss Humphrey lensomters. This reference eye is used as a "test-eye" to determine that the instrument is functioning correctly. To verify the calibration of your instrument, attach the test-eye to the chinrest base. When the base of the test-eye fits firmly against the vertical edge of the chinrest, secure it with thumb-screw (do not overtighten). Align the pupil with the reference markings on the forehead-rest rails using the chinrest height adjustment knob. Using the joystick to align the instrument with the test-eye, press the READ button and compare the measurement with the values on the test-eye. Readings should be within 0.25 diopter.
