New Arrival Handheld Auto Refractometer
HAR-800
Weight only 0.9 KG
with thermal printer
The Hand Held 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.
