Beschreibung
Zusammenfassung:	To provide an optical member in which a patterned shape is visible when viewed from a prescribed angle without impeding the field of vision of the wearer, and a method of manufacturing an optical member permitting the manufacturing of such an optical member. The optical member of the present invention is characterized by comprising a lens substrate 2, a patterning layer 3 in which a prescribed shape has been patterned in a manner covering a portion of the lens substrate, and a hard coat layer 4 formed so as to cover the lens substrate and the patterning layer, and in that a refractive index of the lens substrate 2 is equal to a refractive index of the hard coat layer 4, and differs from a refractive index of the patterning layer 3 by equal to or more than 0.02.
