TV-001 China Auto Refractometer Price Top Quality Optometry Auto Refractometer
Digital refractometer :Refractometer is Combination of modern optics, computer technology, for objective detection glasses refractive status an automation instrument.
Refractometers principle: Computer optometry to objective optometry, its principle and basic same retinoscopy,
using infrared light source and automatic fog visual device to relax the eye, the purpose of the regulation adopts photoelectric technology and
automatic control technology check diopter.
Refractometer accuracy rating :refraktometer accuracy is affected by many factors, such as in patients with head and eye bad cooperation,
moving, eye gaze refractometre target concentration, so as to relax regulation is not enough, inevitably affect the accuracy of diopter results, even double-check varied degree. For children and patients with refractive stromal opacity, refractometry to test error is bigger, can't even check the diopter.
Therefore, determination of the computer on the number of diopter and as the only according to the glasses is not satisfactory.
auto refractometry cannot replace inspection shadow optometry and lens correction technology, provide a beneficial reference for artificial eyes only.
