There are a few plants that will take really low light but even those will find it hard to survive with only 1% UV light. You might want to designate one or two windows for your plants and use the window treatment on the rest.

We replaced the regular fiberglass window screens with solar shade fabric which we found at L's Home Improvement. There are other benefits than just protecting fabrics from fading. They also add privacy to your home. During the day no one can see in unless they press their face against the screens. At night only silhouettes if back lit. Something we didn't expect but are happy with is that grasshoppers can not eat through the thicker fiber these screens are made with. Not sure that's a problem in the city, but we live in the country where every couple years or so we are over run by grasshoppers. I would love to be a kid at heart again, but lately it's been crazy around here. I'm working on getting there again though.

As Mike35 mentioned, you do have to be careful using after-market films because it can void the glass warranty. The two "types" of UV that concern us here on the ground are UVA and UVB (there is also UVC, but it is stopped in the upper atmosphere by the ozone layer). The difference between the two types is frequency of the rays...so why might this be important? Well, first, UVA is primarily responsible for your suntan. UVB is primarily responsible for your sunburn. But, UVA is also the source of those sun-wrinkles that many beach-loving folks end up with...and both A and B may contribute to skin cancer - although there is still some controversy in that area. Second, UVB is stopped by ordinary window glass. If you find a film that claims to stop UVB rays, when applied to a window, then you are not getting any added benefit from the film...your windows are already doing that...UVA on the other hand passes quite readily thru glass. About 95% of the UV we receive on the ground is UVA. Third, while the window films may very well stop better than 99% of UV rays from penetrating into your home, unfortunately visible light also affects the amount of fading damage...not just UV. The amount of potential fade damage that can occur is called the "Damage Weighted Transmittance" (used to be called the "Kratch factor" if I recall correctly - but I may have spelled it wrong). Anyway, the lower the DWT percentage - the lower the amount of fading - or the more protection from sun damage. Blocking UV alone ends up with a DWT of about 65%. Blocking UV by using a tinted LowE coating which will block part of the visible spectrum as well can result in a DWT of 35% - or better. But, the darker the tint the less light transmittance through the window (obvious), so it will affect your view. And the darker the tint the more likely that an after market film will damage the IGU (dual pane glass) due to built up heat stress. My point with all this wasn't to cast a shadow (sorry, the pun was intentional) on what you want, but just to add a bit of information when you are considering the various films that are out there. If you really want to avoid fading, then keep whatever it is out of direct sunlight as much as possible. Coatings and tints certainly help, but they are not close to being 100% effective.

Thanks, Tibb, but I'm going to have this done professionally. Some things I'll DIY, but I just don't think I have the skills or patience to do this job properly. And on my front door, I want it perfect. I'm hopeful the pro is going to have some film that appears to be clear but blocks the UV rays. If I have to go with a slight tint, I may do that. The sun reaches into the LR and strikes the rug and a chair. In the entry, it is blasting down on a chest that I love. Some protection is necessary. In our old house we had woven wood roman shades on similar doors. DH kept them down all the time and it drove me nuts! It was like living in a cave. If I were to put up window coverings, I'm afraid he would keep them down all the time. Best way to avoid it becoming an "issue" is just not to have anything like that on the windows.
