Large Aperture Maddox Phoria Measure

This Large Aperture Maddox Phoria Measure offers a quick method for the measurement of phoria imbalances. Compared to Maddox Phoria Measures previously available, this new product from Good-Lite employs a 48 mm prism rather than the traditional 25 mm prism in order to make it easier to use with children, Low Vision patients and others who may be visually impaired.

Key Features:

• Calibrated with Ohio State Diopter Rule
• Disassembles for easy cleaning
