Reichert Snellen Card Holder, Phoroptor Near Point Acuity Card
Reichert's Snellen Card Holder is a multi-variety phoroptor near point acuity card device, which improves upon and replaces the Near Point Rotochart. The Reichert 16231 Phoroptor Snellen Card Holder has been redesigned to incorporate both Rotochart and Card Holder into a single unit.

The target number is displayed in a separate window above each chart. Made of durable matte-plastic, this rotating double sided test includes:
