What's the best vision you can have?

Question

Is 20-20 vision the best?

Answer 1

20/20 is nothing special.  I'd be willing to be that almost everyone who sees 20/20 can actually see better than that if tested.  Most of my patients can see 20/15 without much problem.  It's not because I'm an incredible doctor, it's because I ask them to read that line.  A lot of docs stop at 20/20.

Another thing to remember that I learned from an old doc is that 20/20 is the WORST you can see and still be considered normal.

Answer 2

With the advent of LASIK eye surgery and the precision it brings to eye surgery, the maximum vision theoretically possible is 20/8.  

20/15 and 20/10 vision has been routinely reported in air force pilots and astronauts.

For the average person, 20/20 is very good vision, whether that is natural or corrected with lenses.

Answer 3

the best ive heard of is 20/10 which is seeing at 20 ft what an average person can see at 10ft

20/20 is ideal and usually most people are born with that and shortly after birth is when vision starts to change and most dramatically during puberty

Answer 4

The ideal vision in humans is 20/20. You want to have this. However, many people have vision better or worse than this. Though very rare, some people see better than 20/20. A common nickname for this is being "eagle-eyed." Far more people see worse than 20/20. If it is significantly worse, they may wear contacts or glasses. Surgeries can be done to fix the problem also.
