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

1. Damp wipe dry2. The instructions say to remove the label marked Step 2. But there is no such label.3. As the instructions said so, I tried to remove the 2nd layer and then everything broke and was destroyed.4. The packaging didn't say "anti-blue light". So I'm wondering if it can actually protect my eyes from blue light even if I can install it successfully.
