  • Patent number: 10167222
    Abstract: UV- and IR-absorbing materials with brown tint for sunglasses are described. The sunglass materials are prepared from a base glass through a post-fabrication process that includes ion exchange with silver. The tint of the sunglass material can be adjusted by controlling the level of ion exchange of the base glass with silver by varying the conditions of ion exchange. A wide range of tint is possible, including multiple shades of brown tint. In a typical process, a base glass having strong absorption in the UV and IR is fabricated and the resulting glass is subjected to a post-fabrication silver ion exchange process to control tint. The post-fabrication silver ion exchange process permits control of tint while maintaining strong UV and IR absorption and adequate transmittance in the visible.
