The shape is square, which works perfectly for those with diamond, oval, and round-shaped faces. The frame colour is purple, which is a good match for green eyes and/or light hair. The lens colour is silver, which reduces glare and improves colour perception. The lenses are covered in a mirrored coating, which helps your vision by tempering bright light circumstances. Polarization has been added to these sunglasses. Polarized lenses contain a special filter that blocks intense reflected light, which, in effect, reduces glare and adds further protection for your eyes. These glasses are equipped with flexible temple hinges, which is a great component for those who often take off their glasses! The material is mainly made of lightweight and durable plastic. These frames have an elegant matte finish.
