FA-6100 Ophthalmological High Quality Ophthalmic Automatic Refractometer
Refractometer The digital refractometer: is a combination of modern optics, computer technology, for objective detection of the refractive state of eyeglasses and an automation instrument.
Principle of refractometers : computer optometry for objective optometry, its principle and same basic retinoscopy, using infrared light source and automatic mist visual device to relax the eye, the regulation objective adopts photoelectric technology and automatic control technology check diopter .
do is Refractometer accuracy classification: the refractometer accuracy affected by many factors, such as in patients with poor cooperation of the head and eyes, movement, gaze refractometer target concentration, so to relax the regulation is not enough, inevitably affects the accuracy of the diopter results, even double-check the varying degree. For children and patients with refractive stromal opacity, the refractometry error for testing is greater, it is not even possible to check the diopter. Therefore, the determination of the computer in the number of diopters and how the only one according to the glasses is not satisfactory. Automatic refractometry cannot replace inspection shadow optometry and lens correction technology, providing a beneficial reference for artificial eyes only.
