I love these curtains! I must admit, I bought them more because they were the right size and not because I especially liked how they looked on the computer screen. But I was so pleasantly surprised - they are really beautiful, especially with a sheer, white curtain behind them (we got a double curtain rod). I can't speak to how effective they are at blocking light yet as we haven't yet tried to watch a movie in the day time or anything like that. But they're at least enought to cut computer glare.
