The ray-ban thalia is a versatile square frame that combines classic style with a modern twist. The unique square shape and slightly curved brow line add an extra touch of sophistication to these frames, while the black color gives them a contemporary edge. These unisex shades are perfect for those who want to stand out from the crowd without being too flashy or trendy--and the polarized green classic g-15 lens offers an additional layer of protection from glare. - frame material: acetate
