Thank you so much for this comment. I can’t believe I didn’t know this, I’ve been inverting my colors & sometimes wearing cheap, non-polarized sunglasses at night — no more!

I had to fiddle with the settings quite a bit to get a 1x zoom w/ the filter, though.

This is a very little-known feature. I work in accessibility and have had an iPhone since day 1. But the only reason I know about this very well-hidden trick is that an Apple employee told me!
