It seemed some folks were interested but there were problems - namely that contact lenses dry out without moisture from the eye, and can be rather expensive.
The thread gave me an idea though - why not just have a removable magnetic iris that could be quick changed?
This was a perfect application for 3d printing. The eyeballs are 3d printed with a natural colored (warm off-white) ABS that is somewhat translucent which is just about perfect for reproducing the sclera. An acetone vapor treatment gives the eyeball a glassy finish - almost glassier than glass. A tiny neodymium magnet (1/8" diam. x 1/32" thick) is glued to the back of the plastic lenses which provides just enough power to hold them in. The lenses can be easily removed with a small suction cup tool - a toy nerf dart works pretty well for this.
These are large 29mm eyes that will go in my mannequin Fiona, but they can be printed at any custom size - 26mm being typical for humans. The plastic iris lenses are available here: http://www.glasseyesonline.com/index.ph ... ucts_id=54
These are inexpensive and not hyper realistic, so they probably wouldn't be good for ultra closeup photography, but they look fairly good at a short distance.
Currently they have 7 basic colors available in the 12mm iris. On the left side is light brown, gray blue and light blue. On the right is intense blue, intense green and a light amber. They also have a very dark brown (not shown) which is good for ethnic applications. Here's a little YouTube showing how they work...
