RetinaGuard Anti Blue Light Tempered Glass Screen Protector for iPhone 8 (4.7 Inch), SGS and Intertek Tested, Blocks Excessive Harmful Blue Light

I use my phone alot for work and often late at night. Prior to using a screen with a blue light filter, my eyes were often irritated after using my phone, especially at night. The RetinaGuard Anti Blue Light screen protector has significantly reduced the irritation that I used to experience. The tempered glass seems to be holding up well and has been fairly resistant to scratches, although I try to be very careful in not letting metal objects come in contact with the screen. It was easy to put on using an mounting frame device from an older glass screen that I had from before.The clarity is excellent and the one thing that I noticed from other screen protectors is that the camera has a cut out so there is no distortion or interference from the screen protector when taking photos.

I have been reading a lot about blue light protectors and so I decided to order them for all my devices. This wasn't easy because a lot of these products don't have reviews and its hard to know what exactly I'm looking for. But I have had this protector on my phone for a little while now and so far so good. It seems strong (I have dropped my phone twice with no scratches or cracks) and it doesn't distort the screen clarity at all. The only thing is sometimes when I am outside and its sunny the whole screen looks very blue, which can be distracting. But phone screens are always hard to see in direct sunlight anyway. Overall I am very pleased with this product so far.

Great product, noticed a difference in eye strain fairly quickly. However, one tap against my car key and it's got a crack already. I've never shattered a screen or a phone so I'm a little disappointed.Updated: This is now my third one and while it protects my screen, it does not stick around the edges. You can see where it hasn't sealed properly despite following instructions. It has been the same with all 3.

This performs exactly as advertised, but I was a little disappointed that it had some bubbles around the edges that took about 2 months to settle out. Not what you’d expect from a premium protector, but it is great otherwise and absolutely worth the extra money.

I noticed since I put this guard on that I get less eye strain, sleep better& and less headaches

EASY TO INSTALL AND MAKES A DIFFERENCE IN MY EYE

Did filter blue light. Only lasted 4 months before it cracked though.

The build quality is good, but I don’t think it helps to reduce bluelight much. For the price I paid, I expect this screen protector to do a better job on helping my eye strain issue, but it doesn’t. Very disappointed.

So I’ve had this cover on since August, it’s now end of October, so 3 months of use and the protector is very badly damaged, better that than my phone I guess, but for the price I would not have expected it to crumble around the edges and crack like it has. So if you are expecting it to last I’d go for something a bit more flexible.

Bought it for my iPhone and love it. Anything to protect the eyes is great.
