Handheld Auto Refractometer
HAR-800: infant mode& adult mode
HAR-880: infant mode, adult mode & myopia mode
The portable auto refractometer 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.
Ideal for babies, seniors and patients with language barrier
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.
It is the neccessory equipment for a doctor to master the refractive status of patients.
