visual acuity test
Chart reading assessment
A visual acuity test measures the sharpness of vision—how clearly you can see details at a given distance.
The familiar eye chart with progressively smaller letters is the standard form.
Results are expressed as ratios like 20/20, meaning you see at twenty feet what a person with normal vision sees at twenty feet: The DMV requires a visual acuity test for license renewal.
