Ideal would be to lower cylinder just for differentials as much as possible, without getting ghosting / directional blur / astigmatism like symptom while viewing screens.

It’s a high ratio to spherical, good idea to find out how much of it you actually need.

Has it always been above 1 diopter, the cylinder? When / how did it start? Any other clues here to suggest how it got as high as it did?
