Description

(1) Technical field [0001] The invention relates to the technical field of daily life, especially sunglasses. (2) Background technology [0002] The current sunglasses are divided into three categories: the first category is ordinary sunglasses. The lenses are divided into two types: (1) general black lenses that can weaken light, have single functions and poor decorative effects; (2) sunglasses with dyed lenses.
