Average quality glasses. Polarization is present, but not very large. About the fact that in the description it is written that they are chameleons, too, I will say, darken very weakly (almost not noticeable).
Glasses are not photochrome: left in the sun-no blackout. At the expense of polarization and UV400 also doubt. Glasses were bought to protect the eyes from scrotum when riding a bicycle. They'll probably do it. We'll check next year.
