Overview
GAOTek 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’t 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 permanent amblyopia. The special model for children testing is the best way for child screening. It is the necessary equipment for a doctor to master the refractive status of patients.
