Mine too, especially if there is snow on the ground. I haven't noticed them changing any slower in the cold either. The only time I've not liked them is deer hunting with snow. As the sun starts to go down, the snow still reflects enough light to keep them darker than ideal for the last 20-30 minutes of sitting in the stand.
