Friends, please advise how to protect furniture from fading. I have an apartment with large windows facing the sunny side, and in a few months, the sofa and curtains have already lost their color saturation. I don't want to keep the blinds closed all the time because I love natural light. Is there an effective solution to reduce the impact of ultraviolet rays without completely darkening the room?

I had the same problem last year when I moved into a bright apartment with panoramic windows. I searched for options for a long time and finally installed UV film from the website https://www.tintfit.com/shop/uv-protection . It blocks most ultraviolet rays, but does not make the room dark. After installation, I noticed that the furniture stopped fading, and the room became a little cooler in the heat. Installation is simple and can be done on your own. For me, it was the best solution without losing natural light.
