I'm not sure if this product is able to be applied to an existing CR-39 lens, but it has many applications for its use. It was developed by PPG, which Transition is a subsidiary of.PPG Photosol
I'm sure you can pick it up at any drugstore...

Do you have contact information for Exenne Optical??
Photochroamtic chemicals is made in England..................terribly expensive and you will still have to do the R&D, to find a way of applying it, which is not covered any valid patent.Originally Posted by nixg
Better stick to your Transition lenses................might be a lot cheaper than playing around with chemicals doing something you have no idea about.

Thanks, Pete
