VizoBlueX 20 -21-21.5 -22 inch Anti-Blue Light Filter for Computer Monitor. Blue Light Screen Protector Blocking Panel 19.5“x 12.1” for LCD TV PC Mac iMac

Edit: Amazon replaced the defected one and the new one is good. The seller also messaged me right away to make sure I received a good one and even offered a partial refund but I didn't want anything extra. Very good customer support from the seller.These panels will make your monitors have extra glare - they are very glossy. May not be a problem depending on light source/direction.Bought 2 of these. One fit and looked as expected. The other one was slightly warped (not a big deal) and had a defect made into it (very noticeable and annoying). I thought it was something I could clean off at first but upon further inspection it's a defect about the size of a fingerprint. Not sure how it made it through quality control. Maybe I can get it replaced. The other one looks great though and seems to help with eye strain.

This review is for the Vizo BlueX 23-24 inch Anti-Blue Light Filter for Computer Monitors. It fits my 23" Samsung Monitor perfectly. It was easy to install - it fits over the top of the monitor without using the adhesive dots that are included. It is very clear and enhances the viewing content (which makes my 13 year old monitor look brand new). Just a quick swipe of a Swiffer duster keeps it clean. I have less eye irritation (a major plus) & my reason for purchasing this item. I am very pleased with this Blue Light Monitor Screen Protector Panel - Highly Recommend

Easy to install, works great, easy on the eyes

Absolutely love it. Easy to install, crystal clear screen protector and if the blue light protection is as good as the company says, then it's worth the price paid. Oh and it fits perfectly

i have been using it for a while and my eyes feel less tired.it should be effective

Seems to work, glare is minimal and clarity on screen both computer and tv not diminished~does what it's supposed to do. Easy to hang on screen without velcro.

Works exactly as advertised. Comes with everything you need to secure it to your monitor screens. Very pleased with the quality, would recommend and buy again if I needed to!

Purchased two of these not for screen protection but for the blue light filtering. We bought a smaller one for the TV in the bedroom and a larger one for the TV in the living room. They both came very well packaged. They both have a little bit of a a gray tint to them which seems to darken the screen a little bit but the picture also is a little bit clearer. We just set them on top of the TV we have not found a need to use any velcro or anything with them to keep them in place. Expensive but a good buy for our needs.
