    • A slit lamp (10) includes a rest for receiving a patient.s face such as the patient's forehead. The slit lamp (10) further includes an optical portion for observing the patient's eye. 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.
    • 裂隙灯(10)包括用于接收诸如患者额头的患者面部的支架。 裂隙灯(10)还包括用于观察患者眼睛的光学部分。 固定光线定位在光学部分附近以将患者的视线导向光学部分。 传感器(30)将其余部分固定并检测用户脸部与其余部分的接近程度。 传感器(30)的输出控制固定灯,从而在检测到用户脸部在其他位置处的定位时开启固定灯。 在一个实施例中,护罩固定到光学部分,并且第一和第二固定灯(28a,28b)在光学部分的任一侧固定到护罩。 第一和第二凸缘在靠近固定光的位置固定到护罩,并且使得每个固定光仅在直接照射固定光时才可见并且使得每个固定光仅在患者眼睛正前方时才可见。
