Fast: Use the joystick to bring your target within range and let the auto alignment feature take over to quickly align and measure each eye, minimizing the time required for set-up and measurement. Multiple refraction and keratometry measurements can be initiated with the touch of a button on top of the joystick.


Easy: The large, tilted LCD monitor allows easy viewing of the screen and icon controls while standing or in a seated position. The motorized chinrest can be moved up or down using the switch at the front of the machine.
