Original vintage 1970s glasses designed and made in England by Pilkington Glass.   They are a quality piece with silver-tone metal frames, a half moon & clear lenses.  They could even be used for optical lenses for an everyday retro look.

These are deadstock, so brand new and completely unworn.  These are sold as a stylish accessory as the lenses will not offer the same Reactolite Rapide protection they originally did.

Length 14.5cm across.
