What is Plusoptix A09 Pediatric Autorefractor about?

The document describes a pediatric autorefractor. It measures the refractive error of both eyes simultaneously from one meter away in children of any age. The autorefractor uses eccentric photo-retinoscopy to project infrared light through the pupil onto the retina. It calculates spherical refraction from the resulting crescent brightness pattern. Cylindrical refraction and axis are determined by repeating the measurement in three meridians. The autorefractor provides rapid, objective refraction measurement
