patent issue

Re: [spiers] patent issue

I have a lot of experience with Transitions lenses. They are indeed very
well protected by patents. Transitions is a joint partnership with PPG and
Essilor. They actually make the photochromics and put them into lenses made
by most major lens manufacturers. So, they don't actually sell the lenses.
They would refer you to lens manufacturers to buy them. They are HQ in
Pinellas Park, FL. If you need more information, I can help you.
