Contacts for astigmatism that can automatically adjust orientation through an active (powered) mechanism would be game changing for the afflicted. Current passive orientating contacts for astigmatism are severely limited.

>Current passive orientating contacts for astigmatism are severely limited.

I have severe astigmatism, have worn contacts (when seasonal allergies aren't horrible) for almost 20 years. Never had an issue that I would even remotely describe as 'severely limiting'. Have I had to blink a few times occasionally to get a contact that's gone a little wonky to correct, yes, but that doesn't justify the incredible cost that some sort of automatically adjusting (probably with some incredibly tiny gyros?) contact would cost. If such a thing were even possible.

You may be an outlier. Personally, I’ve tried a number of different brands and haven’t found one that’s consistent enough for me to get through even a half day of work let alone an hour without at least one occurrence of both contacts rotating out of place at once.

I think I’m not alone because the handful of folks I know with contacts for astigmatism have reported similar issues. Additionally, Reddit is full of similar complaints.

It’s possible that these are all unusual cases. I’ll try to track down a more objective way to review contact lens satisfaction for users with astigmatism later when I get a chance.
