HAR800 Ophthalmic Equipment, Portable Auto Refractometer

Quantity:

Portable auto refractometer
HAR-800

The HAR-800 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.
