I finally broke down and bought clear lens. Some of the friends have them for the overcast days. With snowmaking on those day's there can be a fog that forms over some areas of the mountain. The other week I lifted my low light Glade lens and just had my glasses on for one of those areas. I could see a little better, so I ordered the clear lens. I'll say they do work well. Though last week we skied in one of those clouds, that seemed pretty thick. When we stopped a little way further down, all three of us said, "I couldn't see anything in there". We all laughed. Were in a late 60's, one of the friends has Smith low light lens, the other has Glades with the photochromic lens.
