CE

Note (very important): 

Equiped with liner polarization in default (work with projector only)
We can supply circular polaration if you want this Phoroptor works with your polarized chart vision.

Abstract: 

This device is applicable to ophthalmology department of hospitals and spectacle stores for precision measurement of visual functions such as myopia, hyperopia, astigmatism, eyesight balance, heterophoria, stereoscopic vision and eyesight amalgamation
