A dynamic visual acuity measurement apparatus was designed, and tested for reliability. The apparatus was designed to take advantage of today's computer technology, utilizing the Apple II+ computer and menu driven software, allowing a person with minimal user's experience to reliably measure dynamic visual acuity. Full instructions are described in a thorough step-by-step manner, making the operation of the program practical for the average practitioner. The reliability testing results showed that this dynamic visual acuity measurement apparatus can be useful for testing dynamic visual acuity. The computer generated graphics system provides a method of measurement that keeps many stimulus variables constant, while providing a standard of measurement that is virtually free of operator bias. It requires a minimum of time to use and is maintenance free.
