Hey Rich,
I need glasses for short-sightedness (and to cope with the tropical glare), and have used a Gath helmet with Oakley water jackets since I started kiting in early 2005. They have been great and survived all manner of hard crashes.
Last year I had issues with solar keratoses on my lower lip, so have now added a lycra hood under the helmet to keep the lip 100% covered.
Couldn't give a toss about the style thing - there's usually no one watching you kite on the reef anyway! Much rather stay healthy, keep kiting and keep the kids fed, as you said.
Here is the complete setup:
