Jerry Lee,
You've now asked the same question 3 times. The information you seek is contained in the very first post of the"BEFORE POSTING: Check Here" thread at the top of the forum, where there is a link to the CASA medical requirements. The actual page on the CASA website with the visual requirements is here
