G02C SPECTACLES; SUNGLASSES OR GOGGLES INSOFAR AS THEY HAVE THE SAME FEATURES AS SPECTACLES; CONTACT LENSES (trial frames for testing the eyes A61B3/04; goggles or eyeshields not having the same features as spectacles A61F9/00)
Introduced: September 1968
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.
