27 Inch Blue Light Blocking Computer Screen Protector, Eye Protection Screen Filter Compatible with 27" Sceptre/Dell/Asus/Acer/ViewSonic/Samsung/Aoc/HP/LG Computer with 16:9 Aspect Ratio

I bought this screen filter because one of my nephews was recently diagnosed with macular degeneration due to the very short wavelength blue light he was constantly exposed to with his computer monitor. I also use the computer a lot, so am also at risk just like my nephew. Good quality Screen filters help reduce the risk. Bilberry taken internally also helps reduce it. And I wear glasses, so have UV protection on my glasses, which means some of the short wavelength blue light will also be filtered t some degree, which helps some. So far I have been fortunate and have not yet developed any problems with my eyes from blue light.Now, regarding the filter. Installation took a little more time than expected, but went well. I find that there is very little difference in the brightness of the screen now compared to what it was before the installation of the filter. I did make one mistake in that I started the screen installation on the left side of the screen rather than the right. This is a slight problem because the screen sliders on the programs on my computer are all on the right side, so I should have started installation against the right side instead of the left as there is about a 1/16 inch gap left over and it causes a visible line that runs down the screen where the filter ends. But this is a relatively minor problem. I was unable to get all of the bubbles out, but for the most part that is not a problem. Given the benefits, it is worth it.I definitely recommend this product.

Improperly packed. It came folded in half making it difficult to adhere to the screen and generated multiple air bubbles. I Oder two and o e of the protectors looks like it was either already used or the protective plastic was not put correctly because the top adhesive portion was not protected and dust particle I believe from the packaging was adhere to it. It is also very difficult to get the air bubbles out my husband and I spent about an hour to put the two protectors on the two monitors. We had to partially remove the protector from the screen to be able to get most of the air bubbles out and they still have some bubbles on. I will not buy again.

This screen protector is life saver for my eyes. It definitely works!!!I spend 8 hours behind the computer M-F.My eyes became so itchy and sensitive to the point I couldn't even work. I tried eye drops and blue light glasses but it did not work.Once I bought this screen protector everything changed. I do not have more dryiness and itchiness!Thank you!!!

I bought this because my computer monitor reflects glare and light from a window behind me. It took me a long time to install and it was painstaking to remove all the bubbles. While it’s easier to see because the glare is gone, the screen protector makes texts blurry. Guess you can’t have it all!

Instantly could tell a difference in the brightness and color shades once the product was on. Had a hard time getting the thing to stick to my screen, also having the hardest time getting all the bubbles out.

Was too big and didnt cut easily. and too much bubbles

Yes it comes curled up and won't unroll by itself. I've had this thing for over a. year now and scared to put it on. So, I put it on a flat area, table top flat. Put heavy towels over it and after a couple months it DID flatten out. Then I moved away and forgot about it. So, it was then lying over a narrow object and got distorted by slowly following that shape. Finally it got real flat on its own by keeping it somewhere mostly flat. Next, The little tabs they give you to hold it at the top of the screen, are plain too weak and not grippy enough at all. USE DRAFTING TAPE. I just put it on a little while ago and got most of the bubbles out using a credit card and lens cleaning cloth. The worst bubble, I punctured it in the middle with a sharp exacto knife, with just a tiny prick to relase the air. So, I just read opthomologists say blue light filters don't do anything. But reading below people DO get relief in actual experience. Over the years I'm getting cataracts and its about time I put this thing on my screen, and the anti-glare is rather nice. So, should you buy one of these? I don't know, probably the only benefit is the anti-glare aspect. Installing any of these screens isn't going to be fun, its a hassle and you'll probably never get perfect installion, but with your computer powered up you can't see any of the little bubbles that may be left.

It’s not really what you think it will be. This is not adhesive. There’s visible clear double-sides tape around the perimeter. For a screen that’s not this exact size, there’s no additional tape supplied, so I carefully peeled off the bit from the offcut.The surface has the effect of blurring the text on the screen behind, and leaves some kind of chromatic effect when stuck down. The supplied instructions and installation kit do not seem to relate to the actual product.Now it’s stuck to my screen I don’t think I will peel, but I feel like I should get a refund for this.
