Wow. That’s very special, even here at EM I would say
Axis suggests you have vertical double vision or ghosting without glasses.
If I were you I would choose one from the below options depending on what I can tolerate and how much the cyl disturbs me.
Keeping SPH zero and gradually reduce cyl by 0.25 or by 0.5 each time and alternating it with no glasses when it feels ok
Increasing SPH by half of the cyl dropped: -0.5D SPH and -1.00 cyl (aggressive version) or -0.25D SPH and -1.5 cyl (more cautious approach)
Cold turkey on glasses when possible / existing prescription when not and drop when the existing prescription already feels too much (this version may be super aggressive and may mess up your visual cortex too much due to high cyl value at the start)
Edit: all of these “next glasses options” I listed were meant with the original positive axis at 3 and at 10. And then wichever you opt for, pop it into the converter you found if you are ordering from a place that doesn’t deal with positive axis cyl.
Actually it’s no longer your eyes that are very unusual but your opto’s prescription
Which will work best for you? This is a totally complex area, a lot depends on lifestyle, lights condition, screentime, how much you got dependent on correcting cyl, etc…
Based on my readings your case is the one when it is worth playing around with a test lens kit instead of ordering glasses and try and fail.
And of course, all above is simply my brainstorming for my eyes if they had this prescription. You’ll need to make a decision for yourself considering what you have already learnt about your eyes and vision, and reactions to prescription changes.
This video is a bit difficult to listen to but describes a similar case (though starting from higher SPH higher cyl, but now at 20/20 with some remainder of cyl - very sensitive to bad lights.)
