For sure, year 'round, even in the usually gray PNW. Eyes have always been sensitive to light. I wear them while hunting but try to get them off for the final stalk. I wear glasses like many of us old farts so rather than go with photogray or similar I use wrap arounds "as seen on TV!" I had some HD's but lost them, and replaced them with a similar product called Solar Shields, twice now and they work fine for me.
