Forehead Activator:
Controls illumination inside the Vision Tester. It will only activate the lights when the subject
maintains pressure against the activator, insuring the subject to be at a proper distance for testing. When forehead
pressure is applied to the bar, the green "Ready" indicator will be illuminated on the control panel and the subject will be
ready to be tested.
Headrest Tissue:
The tissue cushions the subject's forehead while allowing maximum hygienic conditions.
Lens System:
The upper lenses are for FAR Point testing (simulated distance of 20 ft.) The subject looks straight
ahead. The lower lenses are for NEAR Point testing (simulated distance of 16 in.) with the subject looking down while
holding his/her head straight. The lenses are easily accessible for cleaning and the faceplate is wide enough to
accommodate wide contemporary eyeglass frames.
Instrument Base: It gives a stable foundation for the vision tester in all positions.
Elevation Adjustment:
Simply depress the button in the base and adjust the instrument to the desired height for each
subject. Release button and the instrument are locked in place.
Observation Doors:
Located on both sides of the instrument, allow the tester easy access to both FAR and NEAR test
slides. A pointer can be used by the tester to assist the subject in identifying the targets. The pointer is held in place by
clips inside the door. The doors are held closed with magnets.
FAR and NEAR Indicators: Located on both sides of the instrument, these lights indicate how the instrument is set to
test accordingly.
Test Dial and Knob:
Located on both sides of the instrument, is used to change slides in the viewing area. The
numbers on the dial correspond to the numbers on the record form for identifying the test slide. The number under the lit
indicator is the number of the test in the viewing area.
Electronic Control Panel:
Operates the functions of the vision tester, power switch, right and left eye switches, Near
and Far switches, Day and Night switches, glare switch, and the peripheral test controls.
Instrument Body:
The Instrument Body is lightweight and is made of flame retardant ABS plastic.
