Aerobatics in glasses.
As I watch Paul Bonhomme's run in Dubai I notice he's pulling 10G with his sunglasses sat neatly on the bridge of his nose.
As I'm about to buy some prescription sunglasses, I'd rather get something that will suit me if and when I start aerobatics, rather than giving it a go and finding that past a couple of G the glasses quickly vacate my face.
Of course the 10G was positive G, I suspect any significant level of negative G and they'd have been straight off.
Has anyone got any thoughts on the most appropriate eyewear? As I said I do wear a prescription, so they do have to be glasses of some sort.
Thanks in advance.
