I tried to cover both bases because I wasn't sure if you were or not. Ha!
I think it'll depend on the person, but I love lenses like this for golf and find myself wearing them when I'm just out in the sun as well. If you like a darker tint though, they do offer a similar one to this that shades things a little more.
Doubt I would need too dark a tint being here in the UK..... we don't tend to get that bright thing shining in the sky as much as you do
