I think it should be corrected if you’re using that eye for focus, manual focus really require a perfect eye (or perfectly corrected) to work well. You could use a contact lens on that eye alone to correct the problem only when you’re going shooting if it doesn’t bother you in everyday life. Just a though but your doctor should be the one advising you in this matter.At least I would prefer that to hang a dioptre on my camera, also I have no idea if the dioptre would correct for astigmatism or not. I have myopia, -3.75 in left eye and -5.5 in right eye and astigmatism in my left eye (-1.75 if I remember correctly), I can assure you I’m blind as a bat without my contacts <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /> But with them on I can see perfectly and focus very well.</blockquote>
