Got lots of cylinder correction, been making reductions, applying stimulus consistently … and after all was well for some time – lately feeling dizzy with those glasses?

Often a sign of improving / reducing astigmatism and cylinder need. 

(no medical advice here … always worth noting since the lens industry has invested millions in lobbying for making clear pieces of plastic somehow be “prescriptions” – this applies to non medical scenarios only)

Below my case specific support response (as available for all members of the BackTo20/20 program):

Knowing how to troubleshoot, FTW.

Note this isn’t always the correct answer.

If you have some kind of medical condition, astigmatism caused by something other than cylinder correction in lenses in the first place, then this likely doesn’t apply.
