These Polaroid sunglasses are sure to hold a special place in the hearts and wardrobes of women everywhere. The cat-eye front, with sinuous lines and a lightweight feel, is the embodiment of informal elegance. It can be fitted with prescription sun lenses, because practicality is fundamental. The temples are minimalist too, with an engraved logo and matching end tips. The use of bio-based and recycled materials marks another step towards green fashion.
