EPHY Privacy Filter 4 in 1 Screen Protector w/Privacy/Anti-Glare/Anti-Blue Light/Anti-Bacterial for Laptop TFT Desktop PC LCD LED Screen - B20W - (20" 16:9-442mm x 249mm), 4 in 1

What a fantastic screen protector. I spend many long hours in front of the computer at work, especially when I take my work home with me. Back in September last year I noticed I started getting a lot headache and my eyes would start to hurt and feel tired/strained when working. Only once I went to opticians to see if my vision was deteriorating he asked me how I was filtering out blue light. I was like what? Lol.I did a little homework on Blue light and realised it was due to the excessive blue light coming from my very old Dell monitor and the symptoms could get worse. Instantly I started looking for an anti-blue light filter and there were none offering this, until I found EPHY’s just launched product offering 4 in 1 protection including anti-blue light. I was sceptical, but I brought one. Once fixing this screen to my screen, I didn’t realise it straight away, but the headaches stopped, and my eyes feel so much better. I hope this review helps somebody else as I was clueless before so I’m sure there are others out there like me.

If you are looking for a privacy screen that prevents people looking over your shoulder standing directly behind you then forget it, they simply don't exist no matter what the product description says.The EPHY Privacy Filter / Anti-Glare / Screen..from Vulu Global does exactly what is says on the box, prevents viewing from either side of the screen at a specified angle. I found the viewing angle of this filter to be even less than whats stated on the packaging (which is great). The screen starts to go dark very quickly even before your view gets to the 30 degree black out angle, unless you have super vision you simply cannot see whats on the screen.It is extremely easy to fit and has a choice of 2 fixings, i used the slide in, slide out fixings since (providing you order the right size) the screen fits perfectly within the screen boarder. The Anti-Glare is a moot point really since most screens are anti- glare these days, in saying that the Anti-Glare works great, I maxed out the screen brightness and the filter just laughed at me!I had a filter previously from a different manufacture which was almost double the price so i was a little apprehensive getting this brand but i cannot see any difference to what i had previously (except the price of course). I'm really pleased with this filter, well manufactured, not too flexible, easy to fit, better blackout angle than stated and a reasonable price.

The filter is an excellent product. I bought it basically for the anti-glare and from the first day I attached it on the screen I saw the difference. From this point of view it’s a fantastic product. However, the fixings and instructions provided are poor. It took me time to find out how to attach it on the screen because the instructions are not so clear. There are two ways. The tabs and the strips. You attach the tabs at the edges of the screen provided there is space on the screen. This method however, did not work on my screen because the glass runs at the very edge of the screen so there is not enough space to attach the tabs. So I had to use the second method that is, the adhesive strips. These are supposed to be double sided adhesive strips which you attach them on the screen and on top of them you attach the filter. Funny enough though the strips that came with the filter were not double sided. I sent an email to the company asking about that and after a month or so they replied by saying that the strips provided were double sided. But I had already purchased from Ebay double sided adhesive strips and used these to attach the filter. It’s a shame that such a good product as the filter is, it does not come with proper fixings. They must have invented a proper method to attaching it or hanging it on the screen rather than “gluing” it on the screen. Apart from that it’s a very good product.

This filter is great. I work in human resources and accounting and it helps me keep sensitive information on my screen secure, in an open office like mine. I can see the screen clearly when sat in front of the screen and it fades to black quickly as the angle from the screen increases, its nuts the screen is completely black from a 30-degree angle right or left of centre,People complaining about not being able to see screen once installed have obviously not removed the protective film, I was guilty of this, then read the instructions again and peeled off the protective filmIf you want to be able keep people from seeing what is on your screen while they are directly behind you, then this isn’t for you, but if you need to keep people from coming up to the side of your computer or just trying to look over your shoulder from an angle, this filter will work great for you.I agree that the hang tabs and adhesive strips that hold the filter to the screen are not ideal, but they do work. I used the adhesive strips and after a few of days, I didn’t even notice them. People complaining about not being able to install the filter, I think is bizarre god forbid you have furniture to put together, because this was nothing.Love the addition of the anti-blue light in this filter, people don’t know how excessive amounts of blue light can be harmful. I brought my little some anti-blue light glasses, so I learned all abut the effects of blue light from the opticiansOverall, love this filter is great. It's well worth the money if you need to protect important information.

As a screen filter it is excellent, it does everything it says it does. The only drawback is the attachment stickers, once the screen heats up it doesn't want to stay attached. If you have an led screen you probably won't have this problem though. I did find a work around for the problem with the sticky tabs. I have left them off and just use small blobs on blue tack on the edge and it works fine. I can't believe all the bad reviews this had received because of stupid not so sticky tabs. The screen protector itself is excellent, I am hoping for one I can use with a graphics tablet now.
