Question: What are the anti glare properties?
Document: Bought 2 of these for their anti-glare properties. I'm using them on 24&#34; Dell monitors and I have windows some distance behind me, so I wanted to remove the glare I was seeing. The filters have 2 sides: matte and glossy. The matte side made the glare much worse, the windows were plainly visible. The glossy side is ridiculous. I can see myself working, like looking into a mirror.
Doesn't really block anyone from seeing what's on your screen but the anti-glare works well. Probably overpriced for what your get.
If not using the other side (opposite the anti-glare side) you can still see screen. But it does help reduce glare that comes from monitor.
Great product. I bought this product for work. The nice thing is that it is also an anti-glare as well as provides the privacy that need.
Yes it is good for privacy protection. but I mostly bought it for anti-glare and it did help that much...maybe %20 less in my eyes redness...
The privacy filter screen I ordered is really good. Screen cannot be viewed unless you are directly in front of it. It also acts as an anti-glare filter, it is easier on the eyes.
I highly recommend this filter if you are really going for the anti glare attributes.Privacy: Like advertised, the screen limits the viewing angle of the monitor so that the person directly in front of the monitor has the best view.
That way there is no reflection from objects behind or next to one's body.So this product can really not be sold as an anti-glare product. It virtually never is.If you need it merely so people standing next to you cannot look see what is on the screen (unless they are behind you) when you're playing games in the boss his time when you're supposed to work for your salary,) this is for you.
Screen works okay as a privacy filter, and very good as a anti glare filter. Screen does work very well as a privacy filter when viewed at angles from side of monitor totally preventing prying eyes. But if a individual is looking over your shoulder, or even in-direct line of the monitor from across the room the information displayed on monitor is not filtered at all.
The screen works for privacy, but unlike the PF22.0W (sold as different size on same link), the reversible option does NOT help with the glareComment on PF22.0W product description offers anti-glare. This is not included on PF19&#8226;Filter is reversible. Choose matte side for anti-glare or glossy side for increased clarity.
Answer: My office has harsh overhead lights that casue a big glare issue on my monitor when I do not have this privacy filter on it.  Without it, there are entire sections of my monitor that I can't "see" because of the bad glare and the the glare also causes me to have migraines.  With the filter I can see every part of my monitor without any problems and no glare-induced migraines.
