Screen Protector Japan Tempered Glass iPhone 5s 5c 5 se[Anti Blue Light] Anti-Glare Screen Film Shield Cover Saver iPhone 5s/5c/5/se[2pack] 2.5d Round Edge/Full Coverage/Case Friendly/Focuses

I was iffy as the product doesn't have anything really mentioning blue light blocking on the package but the screen turns a blue tint in the sun so I can tell it does work.

Doesn't really do much. I see more blue from the sceen with this installed.
