I was under the impression that photochromatic lenses are not a film but a gas sandwiched between two layers of lens material. In my experience they have tended to lose their photochromatic quality somewhat over several years of use, a condition I attributed to gas "leaking" from between, or through, the plastic lenses. Anyone else know anything about this?
