Review on Alphax Stealth Polarized Replacement Lenses by Robert Layne

Not very happy, only bought because they advertised as photochromic. Opened the box, exposed the lenses to direct sunlight and noticed no change. Installed lenses in my oil rigs. I put them on and went outside here in sunny California and still no change. Yes they are gray as advertised but not photochromic as advertised. Without change.
