How does PediaVision
® work?

The measuring principle is based on photo-retinoscopy. Infrared light is projected through the pupils onto the retina. Depending on the refractive error, the reflected light forms a specific brightness pattern within the pupil.

® utilizes an infrared camera that combines auto-refraction and video-retinoscopy. From one meter (just over a yard) away, the camera is used to take a digital photograph. The information acquired is used to automatically assess a child’s vision in as little as five seconds.

What does PediaVision
® screen for?
