A fixation light is positioned near the optical portion to directed the patient.s view toward the optical portion. A sensor (30) secures to the rest and detects proximity of the user's face to the rest. The output of the sensor (30) controls the fixation light such that the fixation light is turned on upon detecting the positioning of the user's face at the rest. In one embodiment a shield secures to the optical portion and first and second fixation lights (28a,28b)secures to the shield at either side of the optical portion. First and second flanges secures to the shield proximate the fixation light and such that each fuixation light is only viewable when directly the fixation lights and such that each fixation light is only viewable when directly in front of the patient's eye. |
