The Apollo lenses contain special crystals that darken when exposed to sunlight.
At night they are transparent, but as light intensity increases, the lenses turn darker to protect your eyes and improve your visibility.
The sunnier it is, the faster it darkens.
The Celerus lens is made of Polycarbonate. This material is so resistant that is used in bulletproof glass, riot shields, and even astronaut helmets.
