Review on i-Deal 2pcs Anti-Blue Lights Tempered Glasses for iPad mini: Protect Eyes from Harmful Blue Light with Bubble-Free Installation by Johnathan Hegie

I think the screen protector probably blocks blue light. I have an iPad mini in a case which is quite small but the screen protector doesn't fit well. It started popping up in corners because it couldn't get under the edge of the hull and got too close to it. After a few weeks, a corner of the tread began to crack. I'm going back to a thinner profile. A great idea. It doesn't seem to be working for me.
