my entire life i thought everything i see was just the way it was and i thought other people saw the same as i saw. later i found out i have astigmatism and when i first wore my glasses everything was crystal clear. felt like an upgrade from 1080p to 4k :D

I have both! My God

Convert astigmatism, into minus lens equivalent. 1) divide the astig, value by 2. 2 ) result = spherical equivalent.
