ZYY Diagonal 27 Inch Anti Blue Light Screen Protector for (W 24 1/8 x H 14) Monitor, Desktop PC UV Blocking Filter for Eye Strain, Hanging Computer Screen Blue Light Blocker 27 Inch Monitor

La pantalla es de mica gruesa, se percibe de buena calidad. Filtra muy bien la luz azul y eso es lo más importante. Pedí la de 27" para iMac. Es importante, una vez la compren y si la van a usar en iMac, envíen mensaje al proveedor para que la pantalla sea apropiada para iMac, pues las dimensiones pueden variar entre las distintas marcas de monitores. No se perciben reflejos de luces que se encuentren incidiendo sobre el monitor. Buena compra, buen precio y envío a tiempo.

I really like this blue light blocker for my monitor, I have a curved screen and this design is perfect because you don’t have to apply anything onto the screen, it just sits over it, super easy to assemble, it’s held up with 2 small rubber “arms” that you put push into the pre punched holes. It’s a perfect fit, so if this is your correct size too, which for me, it is, you’ll love it. The screen itself has a slight tint to it, I guess that's for the blue light blocking, I don’t feel like it’s radically altered my colors and it doesn’t appear to be much darker. I’ve been using it for about 2 months now, and I think my eyes get less tired when I have to be in front of the screen for a long time.

I also appreciate the seller’s customer care

The packaging is neat and the instructions are crystal clear. The screen itself is of high quality acrylic with a grey tint. I could feel the difference on my eyes, almost immediately. The screen does reduces reflections and glare inherent in your computer monitor. But more importantly it definitely has an effect in reducing eye strain. It is easy to recommend this product. Note on size: I have a 27" Apple Cinema display from 2012. The thickness of the bezel of that monitor is almost 1" and there is a about a 4mm gap at the bottom that this 27" screen does not cover. So I would recommend getting a 28" diagonal screen for this monitor. Photography: Because the screen is grey, it does alter the white balance of pictures to the cooler side. My Apple display is calibrated to reproduce accurate colours. I need to take the screen off when editing pictures. (Thankfully this is real easy to do. Just lift the screen off!)

1. Blocks most of blue light. It has made significant improvement in eye comfort. 2. Looks very neat and beautiful. 3. Fits perfectly.
