Relationship between large subject matter areas

Groups A61F 9/02 and A61F 9/04 cover goggles or eye-masks (eye-shields) as forms of protective eyewear worn to prevent particulates or chemicals from striking the eyes, and not having the features of vision correction or protection against high levels of visible and ultraviolet light, which are normally associated to spectacles. Typical examples of goggles covered by these groups are goggles worn while welding, drilling or sawing. Goggles for swimming are covered by A63B 33/00, whereas diving masks are covered by B63C 11/12.

This subclass covers instead spectacles or goggles insofar they have features of vision correction or protection. Sunglasses are covered by this subclass; insofar they protect the eye against high levels of visible and ultraviolet light.
