Description

G02C covers the design, manufacture, and structural features of vision correction and eye protection devices worn directly on the face or eye. This includes spectacles (eyeglasses), sunglasses, and protective goggles that incorporate optical functions similar to spectacles, as well as contact lenses. The classification encompasses frame construction, lens mounting systems, hinges, nose pieces, and other mechanical components, along with optical properties of lenses such as coatings and treatments. Excluded are purely functional optical elements treated as independent components (covered under G02B) and specialized medical devices like ophthalmic surgical instruments.
