What does 20/30 eyesight mean?

Question

I have eyesight of 7.0 in right eye and 7.5 in left eye. How much is 20/30 eyesight? Is my eyesight anywhere near 20/30?

Answer 1

A/B numbering for eyesight is a measure of visual acuity (in other words, the clarity or sharpness of vision). It indicates that you can see at B number of feet what should normally be seen at A number of feet. In your specific case, you can see at 30 feet what should be normally seen at 20 feet.

Please let me know if you have any other questions. I hope this helped.
