This projects a standard infrared image to the retina. By means of analyzing the image on the retina, it can measure hyperopia, myopia, astigmatism, axis and cornea curvature. Instrument can also measure the pupil distance, axis, farsightedness, nearsightedness and more. Auto Refractor/Keratometer uses the most advanced technology to provide accurate measurements. Instrument has a 7”TFT LCD touch screen in which is convenient and at the same time easy to use.
