Coke-bottle glasses?

Anybody know of any thick, "Coke-bottle" eyeglasses props? I have an image I'm thinking of doing, but I need the lenses to really pull it off. Free or cheap would be much preferred. I'm a Poser user, by the way. Character doesn't matter because I should be able to make such a prop work with any figure.
Thanks in advance!

I haven't seen anything like that. I made something similar for a character in Max once. Can't access the file now though and I remember having trouble at the time getting the coke bottle look to work right. It was ok, not quite right.
Okay, hazarding a guess- use a primitive and insert inside a pair of regular glasses, then change the surfaces for the transparency, etc. In other words, cheat.
Interesting idea!
The trick is getting the curve and thickness right to get the full "coke bottle" effect.

Slosh's Spex have materials and shapes for the lenses that may help.
Those actually look workable with minimal kludging - to me anyway.
That is awesome. The only question is whether or not they will convert to Poser well? The materials, I mean.
As a sort of training (I'm not a modeler) I tried to change ptrope's specs in Blender.
Don't know what gives the best effect concave or convex?
Convex obviously is the effect I want, but how well that effect works in the CG world, I don't know. But then I can always create or enhance the effect in Photoshop, I suppose.
Sorry, I'd forgotten that you would want a Poser version. Spex doesn't have a Poser Companion File listed, I'm afraid. All you need is a flattened cylinder (or whatever fits the frames) with concave surfaces, as viewed from the eye side, more concave on the eye side than the outside and then apply refraction in the Material Room.
one thing I found while developing SPEX was that the shape of the "lens" really had very little to do with the magnification effect. In fact, the presets I created for the different strengths were all based on changing the Index of Refraction for the lens material. 1.0 had a zero magnification effect, while 1.1 and greater made the coke-bottle effect greater. Numbers larger than zero, but less than 1.0 made a demagnification of sorts. Just experiment with that setting (make sure you choose a shader with this option. Uber-surface base is a good one in Studio, not sure about Poser).
The Spex seem to work great in Poser except for possibly the lens settings, but I need to do more testing first.
For the lenses, Maclean's Everyday Morphing Primitives (available here at DAZ) can be helpful. Together with a glass shader (e.g. Tofusan's free 'Realistic Glass Shader with Absorption', available at sharecg) you get nice effects.
Some test renders in Poser. Glasses work fine. Many of the materials work fine. The more complex shaders (including the lens effects, don't translate properly.
