I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I don't know if 100/100 is possible.

Usually the first number is 20 and the second varies.

*  20/20 - Normal vision. Fighter pilot minimum. Required to read the stock quotes in the newspaper, or numbers in the telephone book.

* 20/40 - Able to pass Driver's License Test in all 50 States. Most printed material is at this level.

* 20/80 - Able to read alarm clock at 10 feet. News Headlines are this size.
* 20/200 - Legal blindness. Able to see STOP sign letters.

100/100 is the same as 20/20 as we are dealing with fractions.

20/20 is considered normal human vision & other figures are quoted relative to that figure. So 20/40 is half as good as the "standard" & 40/20 is twice as good as the "standard".
