The phone screen is polarized opposite of you glasses. You could try to find some glasses which are polarized in the same way as the phone or do as I have and add some polarized clip ons which have been trimmed to leave the bottom part of your view clear. I find this to work very well for flying. When I look up at the sky, the polarized lenses keep my pupils from contracting too much. When I look down, I can see the screen better than with sunglasses of any kind. View attachment 26232 View attachment 26233 View attachment 26234
Great tip, gotta find one of those.
