Zusammenfassung:	FIELD: manufacture of optical members. SUBSTANCE: introduced into silicon material of the lens is additive of silicon pyroporphyrin dihydroxide and silicon tetrabenzoporphyrin dihydroxide in ratio of 10:1. Additive is introduced in the process of component mixing in the amount of not in excess of 0.01 mas.% of the total mass of material. EFFECT: protection of eyes from harmful effect of near ultraviolet and violet light with the wave length of 350-450 nm. 2 cl, 2 dwg Изобретение позволяет защитить глаз от вредного воздействия ближнего УФ и фиолетового света с длиной волны 350-450 нм за счет того, что в силиконовый материал линзы введена добавка из дигидроксида пирропорфирина кремния и дигидроксида тетрабензопорфирина кремния в соотношении 10:1. Добавку вводят в процессе смещения компонентов в количестве не более 0,01 масс % от общей массы материала. 2 п.ф-лы, 2 ил.
