How well your eyes perform varies from person to person. If you’re like me, your vision isn’t that great. But there are some who have 20/20, pretty much average vision, and some may have even more flawless, clear vision.
The Snellen chart is the most famous vision test, but there are alternative ways to know how well it is that you see. This test is one of them. It evaluates how well your eyes can interpret, differentiate, adjust and focus on the images it’s taking in.
If you don’t do well on this exam, it may be time to see an eye doctor for a professional exam.
