Just been watching the 2013 ISSF Mens World Cup Trap finals (Al Ain) on youtube and there's a shooter called Andreas Scherhaufer (Austria). He was wearing shooting glasses that I have not seen before and I was wondering if anyone knows the make? They have what appears to be a very robust adjustable nose bridge support that prevents the glasses from slipping, and can be adjusted to sit quite high. They look a bit weird but highly functional.
