I grew up inside an optical shop. My mother likes to tell how, as a kid, I would watch eyeglasses being assembled, play with the tools, and draw on the back of service order slips.

March 18, 2026

Quick Answer: Visual acuity is the eye’s ability to distinguish fine detail at a specific distance. It is measured with a Snellen chart, and a result of 20/20 (6/6 in meters, or 0.0 on the logMAR scale) indicates vision within the accepted normal range. Results below that threshold may point to refractive errors such as myopia or astigmatism, or to conditions that require an eye examination.
