RetinaGuard iPhone 6, 6S Anti Blue Light Tempered Glass Screen Protector (Black Border), SGS and Intertek Tested, Blocks Excessive Harmful Blue Light, Reduce Eye Fatigue and Eye Strain

While the filter claim regarding this product seems legit as my eyes felt less tired when using, its durability and quality claims are at great odds with reality.Gentle placing of phone on desktop apparently causes enough vibration to create cracks down he edge of this glass. The bottom edge of the glass is also so rough that it has actually caused scratches on fingertips from contact.This product will not last very long and is therefore not worth any cost. In addition, play close attention to hinted at ‘color change’ with these kind of filters on phones; In low light there is no issue, but in sunlight or well lit rooms, you phone display will look very cloudy and odd. Purchasing blue light filter glasses is definitely the better play.

was ok

Loved this screen protector. I am constantly dropping my phone and the screen protector took all the damage. I dropped my phone (screen first) on a small sharp rock. As I further examined the protector I noticed it had cracked and when I removed it my screen was in excellent condition. Saved me hundreds on getting y screen replaced.

Works great just like the Ad says!!

Very satisfied with this! the screen is great and is very smudge proof, best of all it looks very very minimal, doesn't look like a screen protector is put on from a short distance.
