DEFINITION

Classification: 351/44

(under subclass 41) Subject matter, including light absorbing lenses such as polarizing or colored lenses either framed or rimless, to shield the eyes of a wearer from the glare of the sun or from other undesirable or harmful light rays.

(1) Note. For classification here the lenses need not have diopter characteristics, but only general light modifying characteristics such as light filtering, polarizing, or absorbing. See Class 359, subclasses 483+ for polarizers, subclasses 601+ for optical elements and systems for reducing glare and subclasses 885+ for optical filters.
