摘要： In an eye test apparatus of the type having a single examination area, an improved view port is disclosed having a view port casing and a mounting apparatus arranged so that the view port casing is movable between a first and second active positions. In a first active position, the casing receives a patient's forehead so that a patient's right eye is aligned with a examination area, and a second active position wherein a casing receives a patient's forehead so that a patient's left eye is aligned with the examination area. The casing is specially configured to occlude ambient light and to accommodate a patient wearing eyeglasses. The eye test apparatus may further have a position sensor system for sending the present position of the casing. In one embodiment of the invention, a control unit is provided which is responsive to the position sensor system so that administration of a test to a patient is permitted only if the casing is in an active position, and may further be made responsive to the sensor system so that data captured during the test by the control unit is automatically categorized according to which eye is currently being tested.
