DEFINITION

Classification: 351/41

(under the class definition) Subject matter including an ophthalmic element or elements such as a spherical or cylindrical lens, a filter, polarizing element, or prism interposed in the path of vision of one or both eyes for correcting vision defects or abnormalities or protecting the eyes from undesired rays together with structure for positioning or supporting these elements from or on the head of the user in correct operative position.

(1) Note. The lenses of this subclass give usually a

particular ophthalmic result in cooperation with the eye as opposed to lens systems such as used in cameras, microscopes or telescopes which may operate independently and without producing a corrective reaction in the eye or its element.
