ScreenShield

The screen on your phone, tablet, laptop or other touchscreen device is probably the part you use most during the day. You touch it constantly, it goes in and out of pockets and bags, and it picks up fingerprints, dust and contact with whatever surfaces it meets along the way. Sometimes it also comes up against keys, other things you’re carrying or surfaces you weren’t expecting.

A blue light blocking screen protector filters some of the blue light coming off a display. ScreenShield calls Optic+ Blue Light Blocking its most innovative range, and it filters light in the blue light range as well as UV light.

Your iPhone 11 does a lot in a day. Messages, work emails, a scroll on the couch, a photo of the dog doing something daft. Most of us look after the front screen, but the back tends to get forgotten, even though it’s the side that scrapes along benches, bag bottoms and café tables.
