Auto Refractometer/Keratometer

The Auto Refractor/Keratometer projects a standard infrared image to the retina. By analyzing an image of the retina, it can measure hyperopia, myopia, astigmatism, axis, and cornea curvature. This instrument can also measure pupil distance, axis, farsightedness, nearsightedness, and more. Auto Refractor/Keratometer uses the most advanced technology to provide accurate measurements.
