High quailty sunglasses if its too bright to shoot comfortably, otherwise I just use clear.
I used to think that way. I was a lot younger then. You will get over it as you see the advantages.
Good intentions will always be pleaded for any assumption of power. The Constitution was made to guard the people against the dangers of good intentions. There are men in all ages who mean to govern will, but they mean to govern. They promise to be good masters, but they mean to be masters.
