The unblinking eye is the symbol of the Cao Dai faith, founded in 1926 in Viet Nam. "Cao Dai venerates a host of different figures including Victor Hugo, Sun Yat Sen, and Trangh Trinh, a 16th century Vietnamese poet and philosopher. Its ethics are based in the belief in the reincarnation of the soul." There are 7 to 8 million adherents, mostly in Viet Nam.
