What do the numbers mean in a vision test?

An eye chart measures visual acuity, which is the clearness or sharpness of vision. The top number is your distance in feet from the chart. The bottom number is the distance at which a person with normal eyesight can read the same line. For example, if you have 20/30 vision, it means your vision is worse than average.

Which is better 20 20 or 20 15?

Normal vision is considered 20/20 vision. This means you can see things at 20 feet that a person with normal vision can see at 20 feet. If you have 20/15 vision, you can see things at 20 feet that a person with normal vision can see at 15 feet. This means that 20/15 vision has greater acuity than 20/20 vision.

What does it mean to have 20 20 or 20 15 vision?

Having 20/20 vision means you have normal or average, vision. Some people have vision that's better than 20/20, like 20/15 vision or 20/10 vision. This means that you can see something 20 feet away (like a line on an eye chart) that most people can see when they're 15 feet away (20/15) or 10 feet away (20/10).
