Patent attributes
A slit lamp includes a rest for receiving a patient's face such as the patient's forehead. The slit lamp further includes an optical portion for observing the patient's eye. A fixation light is positioned near the optical portion to direct the patient's view toward the optical portion. A sensor secures to the rest and detects proximity of the user's face to the rest. The output of the sensor 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 secure to the shield at either side of the optical portion. First and second flanges secure to the shield proximate the fixation lights and such that each fixation light is only viewable when directly in front of the patient's eye.
