FIELD: glass production. SUBSTANCE: method of producing glass with refraction index gradient involves the steps of: providing a glass plate with a surface layer of photosensitive crystallizable glass, sequentially exposing the plate to produce exposure gradient along the surface, thermal treating and ion exchange treating in molten metal salts. Method is characterized in that glass with smooth distribution of reflection index in the plane to be worked is obtained. EFFECT: enhanced efficiency. 1 dwg
