I also notice a difference in the drops, especially with a headwind. The think that keeps me from staying there for more than ten minutes at at time is that I find I am always looking over the tops of my prescription sunglasses. So, I don't have the sunglass effect and I don't have a clear view. In order to look through them instead of over them I have to raise my head and neck and that hurts after a bit. I've tried lots of brands and styles but still can't find anything that really works for this problem.
