Includes Red and Green color bars for an easy and helpful place to start administering the test. Sloan optotypes are highly calibrated to a 5x5 grid. This grid helps to create a un iform difficulty throughout the 10 optotypes. Each optotype takes up a similar space and creates a uniform blur when they are out of a patient's visual acuity range. This is an essential factor that makes Sloan optotypes so reliable and accurate in visual acuity testing. Show more
