What Is Visual Acuity?
Visual acuity refers to how clearly you can see fine details at a certain distance. It’s commonly tested using the Snellen chart, which displays letters or symbols in decreasing sizes to gauge your vision precision.
How Do Visual Acuity Tests Work?
-
Testing Process:
You read letters from a chart placed typically 20 feet away. If unable to meet this distance, the test is adapted accordingly. -
The Snellen Chart:
Features lines of letters that become progressively smaller. The smallest line you can read determines your visual acuity score. -
20/20 Vision Explained:
“20/20 vision” means you can see at 20 feet what a person with normal vision sees at 20 feet. A rating like 20/40 indicates you see at 20 feet what others see at 40 feet. -
Test Procedure at SpecSMART:
You cover one eye at a time to test each eye’s acuity, helping identify vision issues per eye.
