Originally posted by wrench.doozer I agree cleaning would be paramount. Also most coating labs would serve the eye glasses industry, so the trays, lens holders, etc. would be set up for 'uncuts', say about 50mm or so diameter. I've thought about this, as I've been to our local lab called Optogenics on an interview once. But this is all academic.
Also, you're going to get a "run-of-the-mill" coating unless you can spec a high quality lens formula, no way comparable to what is applied to most photographic lenses (multi-coatings and a protective layer).
