Remember that Jake’s comment about not monkeying around has a follow-up of “until you know what you’re doing.”
If you have a complex prescription (including things like astigmatism and/or a diopter gap) there is no way you can make meaningful progress toward 20/20 without messing with the diopter bubble. However, it is important to read and learn enough to understand how and when to make changes. That way you can make the decision for yourself when you’re ready to try it. This is all a DIY process so plan to experiment a lot and expect to make some wrong choices now and then. Mistakes can slow you down, but what we’re doing is generally pretty safe.
In my case, I have the trifecta of moderately high myopia (minus sphere), astigmatism (minus cylinder), and a large diopter gap. So my path to 20/20 is going to be very different than most people’s path. I’m going to have to start “breaking the rules” (there are no rules, just recommendations) quite soon by beginning to equalize straight away in order to close the diopter gap quickly enough to get to binocular balance before I lose my differentials in the low diopters (or things will become harder).
In your case, it is up to you how you proceed. But the recommendation is to do your CYL reductions separately from your SPH reductions (and space the CYL reductions out) to avoid changing multiple focal planes at once. This usually means dropping 0.25 CYL in differentials, then 4-6 weeks later (or when you’ve gotten used to it) drop the same from your norms, then do two cycles of binocular SPH drops before dropping the next 0.25 of CYL from diffs, et al. You don’t need to touch SPH when you’re dropping -0.25D of CYL as part of a normal cycle.
Note: Since 0.25 CYL is hard to see, some people can drop 0.50 CYL in each cycle (which would be equivalent to a -0.25 SPH drop). But you’ll have to experiment to see what your visual cortex will handle.
