This is a fantastic value, great quality set of sunglasses that come complete with a soft case to keep them safe.
Lenses are made from polycarbonate to give first-rate optical features, excellent impact resistance and extraordinary lightness: polycarbonate lenses also have a low refraction index and are scratch resistant.
Off-centre lens, the axis of the lens is aligned with the focal point of the eye so your eyes won't get tired during use.
The lenses are treated to make them perfectly smooth so any drops of water simply slide off, leaving the surface dry and free from water prisms so you will always have perfect visibility.
The specific ergonomic shape of the nose pads ensure that sunglasses sit perfectly on the nose.
