Another thing to do to minimize thickness is to work with bridge width and lens size to make the optical center of the lens close to its physical center. Many of my lenses have their optical centers closer to the inner edge. With a minus lens, this makes the outer edge thicker.
My best metal pair for thinness has 38 mm lenses with the optics very well centered. Even though they're made from CR39, the lenses are pretty thin. Also keep in mind that to get that last few percent of extra thinness with a more exotic material will likely add a lot to the cost (similar situation to buying hi-fi music equipment), as well as having worse optical quality. -- Check us out at the oft-updated http://glassyeyes.blogspot.com!
