What is visual acuity?
Visual acuity (VA) is a measure of the ability of the eye to distinguish shapes and the details of objects at a given distance. It is important to assess VA in a consistent way in order to detect any changes in vision. One eye is tested at a time.
A visual acuity test is an eye exam that checks how well you see the details of a letter or symbol from a specific distance.
Visual acuity refers to your ability to discern the shapes and details of the things you see. It’s just one factor in your overall vision. Others include color vision, peripheral vision, and depth perception.
