VISUAL ACUITY MEASUREMENT STANDARD
This class of thresholds can be measured using short bars, Landolt rings, gratings or other targets B 1 1 In clinical measurements resolution capability is inferred, but the exact relationship may be at least partially obscured by the added, complex factors mentioned earlier B 2 Once measured, visual acuity findings must be interpreted
