 the glasses over the years have always been this, you know, I have them there. I'm going out with them. Obviously, it's probably a sunny day when I'm playing, so I'm going to be wearing sunglasses anyway. But the fact that you mentioned that the polarization is what messes up a lot of putts, I find very interesting because, again, golfers don't think about that. Right. Or they think it's not going to have that much of an impact, right? Like how much is it?
