Reverse Letter Visual Acuity Test Chart
The Reverse Letter Visual Acuity Test Chart is designed to be read by the patient through an Ophthalmic Viewing Mirror in order to achieve a greater viewing distance. It is best used when exam room space is too limited for a regular 20ft distance eye chart (OS-1930) and this reverse letter chart is an exact mirror image of that classic eye chart.
The OS-1920 Reverse Letter Visual Acuity Test Chart is made of extra strong, non-reflecting, matte finish cardboard, with a brass eyelet for wall mounting. Red and green bars not only serve as a reference point, but also hint as to a patient's color perception.
