Getfunky: - I do most of my kiting over coral reefs, so the polarised lenses are essential to look into the water and see the coral, tigersharks etc.

Evidently, the problem is mainly with the optical lab that Seaspecs are using to supply their prescription lenses, however their quality control seems pretty poor (ie. polarisation wasn't checked before glasses were made and before they were sent) and their willingness to help an unhappy customer was pretty slothful.
I'm sure if I kept badgering them then maybe, I would eventually get a set of glasses that worked, but really, I cbf.
I have a contact in the industry that has organised a set of water jackets from Oakley Europe, so hopefully that sorts the problem. If not, then Jason I will talk to you.
