I own an iPhone 5 running ios7 beta 5. I also have an iPod touch 4th gen (5.x.x) and an iPad mini (6.1.3). I recently lost my sunglasses, in a pinch I bought a set that were the style I liked. These ended up being polarized glasses, and this was my first time ever wearing polarized sunglasses. After having them on for a few minutes, I checked my phone, to my surprise, my screen had a very unusual effect! The contrast became insanely drastic while viewing through the glasses, and changes as I move the screen back and forth. I instantly thought that it was strictly from the glasses and that all of my devices would appear similarly. Not the case. All my other devices look the same with or without the glasses on. Even another iphone 5 running ios 6 did not have this effect. I can't figure out why this happens, and I can't fully describe in words how unusual it looks. If you have ever worn polarized glasses, certain things have an unusual look, like car windows, etc. I just find it interesting that ios 7 seems to be the difference in how the display appears through polarized glasses. It is extremely different. Any thoughts? Anybody else experience this?
