I'm a big fan of the old B-7/AN6530 goggles. You can buy a new face pad for them, and they have a nice pair of curved lenses. I have glass lenses in both clear and amber. There are only two drawbacks:
1) I can only wear them with my contact lenses in, no glasses.
2) Until your face is matched by the face pad by repeated wearing, it can be a bit hard on the bridge of your nose.
They can be a bit tough to find, and they are pricey in good condition. I found my pair without lenses, face pad and strap, and in bad need of replating. I had them dull nickel plated (too many $$, I think it was around $75 a number of years ago) and found a set of lenses and face pad from Jon Aldrich in California. The cushions and lenses are still available from his son, Curtiss. The web site is at: http://www.aviation-antiques.com/1941-military-10.html
I'll post more on goggle and a photo of the 6530's later in the day.
