Question about Gardinia Easyfix Plissee

I think so. My desk is by the window, and so far I've hardly been able to work in the afternoon because of the sun. Now, with two of these pleated blinds, it works fine. It's still bright, but it works fine. Even with the white version!

Yes and no, it depends on the position of the sun and how "sensitive" you are. :-)
I've had the pleated blinds for a few months now because I have my PC monitor right in front of the window. I'm very happy with it because it's still bright in the room when the pleated blinds are open. However, if the sun shines directly on the window in the morning, then of course it still has an effect - but still better than without pleated blinds.
I can highly recommend them, but they are not 100% glare protection. I would at best recommend those Gardinia pleated blinds that have a film on the "back" - they are possibly even a little better. At least that's what I imagine...
