I've always been able to see out my windows, and we fly into really cold places like Moscow etc, but I do agree that they're VERY tiny, and they kind of magnify everything outside so it looks like it's way closer than it is, which could also be deceiving in an emergency eg. you think the danger is closer than it really is, but I can see the point of them being small for decompression also. I never knew that was the reason why!
