Howell Phoria Card™

Both Near and Far come with a single 6 PD stick prism.

These cards allow direct measurement of the distance and near phorias in real space or with a phorpter. The patient simple has to tell which number the arrow points to. Any odd number (in yellow) shows esophoria while the even numbers (in blue) shows exophoria. An AC/A can quickly be determined with trial lenses.

The reverse side of the near card has a X-Cyl target, and a variety of letter and word targets.

Near card is about 12" wide.

Distance chart is about 24" wide.
