Hi colhermit,
I worked in the Optical world (Optometrists) for over 20 years.
At first they all refused to accept there was a place for simple, ready made, Reading Glasses.
Some still believe that, but the smart ones realised that for some people that was really all they needed so why not have them, on hand in the practice, if it turns out there is a sale that might otherwise walk out the door.
If you can't beat them join them and be a hero!
Same is true for Podiatrists with inserts for shoes, and probably other businesses as well.

Let's hope this marks the beginning of a big turn around in market sentiment. There are probably other markets we haven't even thought of where they might want such a product as ours.
Cheers,
