    What does a visual acuity score mean?
    Visual acuity scores are usually written as a fraction. These test results describe your ability to see an object 20 feet away compared to a person with normal vision. For example, 20/20 vision means seeing an object clearly from 20 feet away. The medical term for this is emmetropia. What Vision Problems Affect Visual Acuity Scores?

    What is a good visual acuity?
    Normal visual acuity (which is better than 1.0 (20/20) ) is represented by negative logMAR values. The VAS scale (VAS = Visual Acuity Score) serves the same purpose. Its formula is: 100 - 50 x logMAR or 100 + 50 x log (V). It is more user friendly, since it avoids decimal values and is more intuitive, since higher values indicate better vision.

    Note that the scales in the tables extend well above the reference standard (1.0, 20/20, the ability to recognize a letter subtending a visual angle 5 min. of arc), since normal acuity is often 1.25 (20/16), 1.6 (20/12.5) or even 2.0 (20/10).
