Eye Protection Screen Protector Compatible with Apple iMac 21.5 Inch, FORITO Blue Light Blocking Screen Protector Compatible with Apple iMac 21.5"

Installed this on a brand-new 21-inch iMac. It fits perfectly and eliminates glare. The instructions were easy enough to follow. As others have suggested: Take your time during the installation. It takes just a few minutes. Initially I was concerned because even though I was very careful about peeling off the backing (first side) a little at a time and affixing the screen protector to the iMac using the provided "slicker" to remove any air bubbles, there were still about 20 small (approx. 3/16 inch diameter) air pockets remaining -- and I could not smooth them out. However! by some miracle, they disappeared on their own after several days. Amazing. P.S. As others have noted: Remember to remove the second side of "backing" (plastic covering) once the screen protector is in place!

This simple product has made a huge difference. Any Mac user will tell you that those beautiful screens lead to crazy reflections and unwanted glare. We just purchased a new imac and after 1 day my wife was ready to return it because the screen was giving her headaches. I took a chance that this product would help alleviate the issue and it did. Instantly. A huge difference in the way we work now.Installation was tricky and is better with two people. I did it myself and it took a little effort to get it aligned properly. It is a good idea to perp the screen and blow away any dust. The protector had everything you need to combat dust but it is still a challenge.The squeegee that is used for pressing bubbles out needs to be used gently or you can damage the cover.We were able to get it on with only minor,tiny specs which are only visible when the screen is completely off.

The "dust-absorber sticker" was not included. The "application card" was not included. Only one end of the packing tube was secured, the other end was open. Was there supposed to be a cleaning cloth as well? If so it was not included. It did take two people to apply it.Most IMPORTANTLY: It caused blurring of all text/print causing eye strain after only a few minutes of use. It is completely unusable by either of us.

I am having severe problems with my eyes from writing reports on the computer everyday. So I needed something to to reduce my blue light exposure. The product arrived in a very secure package tube. I would say it was a bit overkill and the company could probably save money if they reduced the hardness of the cardboard. Anyway, the film was non descript. The instructions were minimal and useless. I didn't know what I was supposed to do with these "guidelines" they included. I finally figured it out and I had all these bubbles underneath. I did my best to get rid of them but they are still there. I don't care, they don't interfere with it's use. The screen just doesn't look as nice when not in use. I think it helps. It's hard to say. I still get headaches but I do think it cut down on my glare.

I still have a few bubbles from installation, and I thought the instructions were vague and not great. But overall, the product works and serves its purpose.

It works well on my iMac. My eyes feel a lot better and the retina screen is still very clear. Relatively easy installation. There are a few bubbles, but once my computer is on, I do not notice them anymore.

The item is good quality, comes in good packaging and but it would be nice in the future if you provide even just a small spray for the screen. Before the item is being installed

Study up on blue light effects and you will understand why this is a must. I reviewed because I was skeptical from other reviews. Not only did this do exactly as stated but it has reduced glare as well. The results should be obvious immediately to you upon applying this!!! Thank you! I am going to purchase for my tvs now!!!
