I would like to get some clarity from someone who has a little more experience with the printable astigmatism tool found on endmyopia.
Measuring Axis Number
Step 3. Focus on the indicator dial line, slowly moving back until you start to see blur.
I’m assuming the indicator dial line is the one with the arrow?
Step 4. Turn the dial until the line with the arrow becomes clear.
During this step do I continue focusing on and following line with the arrow while turning it? Or am I supposed to focus somewhere more central?
Measuring Cylinder Number
Is it necessary to measure cylinder with the tool in the same Axis degree position for the eye being tested?
It’s possible that I’m over complicating this, just want to be sure I’m measuring correctly.
