What does it mean if your vision is 20/17?!


Question: What does it mean if your vision is 20/17!?
I know that normal vision is 20/20!. What happens if it's higher or lower than normal!? Ex: High 20/40, Low 20/10Www@Answer-Health@Com


Answers:
20/20 vision means you can see at twenty feet what most people see at 20 feet!. 20/10 on the other hand means you can see at 20 feet what an average person has to be 10 feet away to see!. Naturally if the second number is higher than the first than you have poor vision!. The opposite is true if the second number is lower!.Www@Answer-Health@Com
