the numbers. here is where you can kind of quantify the
problems I have with my left eye. the ASTIG measure in the top shows that I
have a minimum of 52 d (diopters)) of astigmatism and a max of 60
the 3.0 MM ZONE is 3 millimeters from the middle of my eye and as you
can see it is +/- up to 25 D which is a very large range.
in the 5.0MM ZONE the Steep axis means how steep of a hill. imagine
driving up a 47º hill this is why a rigid contact couldn't compensate.
the last number of importance is the THINNEST this is the measure of
the thickness of my cornea this is less than 50% of the thickness of my
cornea at it's thickest
