13. Handheld Auto Refractometer HAR-800

Hand-held automatic refractometer (Handhold Auto Refractometer HAR) based Shack-Hartmann wave front sensor to detect eye refraction principle to determine the vision. Handheld vision tester is mainly used for the preliminary determination of eye refraction and screening, with objective, accurate, fast, etc., automatic, noninvasive; requires a minimum of cooperation, not only applies to groups with strong, but also with in children, the elderly and other groups with not strong. This solves the ordinary computer refractor subjects who need close cooperation with many of the issues and convenient movement. Even if the subjects were wearing glasses or cataract lenses, you can at a distance of 35cm away his safety and objectively detected diopters.

The HAR-800/880 vision screener can check the refractive error precisely for different groups of people using the ultrasonic ranging, cross line, flashing light and sound technology and then to find out the probably potential refractive problems.
The HAR-800 vision screener has so many merits, such as portable, fast and accurate testing, non-contact and non-injury to your eyes. It is fit for the refractive screening of huge population since that 5 second is enough for both eyes test. We all know that the refractive status is very important for children just because that if doctor can not find the long-lasting refractive error and cure it properly, children would become amblyopia sadly someday or lose the best chance to treat the lazy eye and finally become the permanent amblyopia. The special model for children testing is the best way for child screening. So it is not only for the adult, but also for the infants and handicapped patients.
HAR-800 vision screener–the optimal weapon for doctor to master the refractive status of patients.
