Prosthetic Eye

[curious aardvark]

can't be done.

You don't 3d print glass - well at least not at the moment.

The only thing around that I know of is printing with material containing glass powder and then sintering that, which burns off the carrier material leaving behind the bonded glass.

What you want is someone who makes glass paper weights.
They could easily reproduce eyes in glass.

You can print with resin clear enough for optics - but as far as I know there are currently no full colour resin printers on the market - quite probably something under development. But certainly nothing commercially available.
