After a lot of messing about, Oakley have told me that they can't make up Flak Jackets (or indeed any of their range that I'd want) in my prescription after all, so after a £300 refund I'm back to square one.
Any other suggestions that are likely to be available for my relatively mild prescription (total power -4.5)? I know Rx Giro Filters are available from the US, anyone got any feedback on those?
P.S. I tried inserts and contacts before and wasn't keen so it has to be direct glaze.
