The Madara eternal Sharingan lenses appear to have a ring around the pupil in their kaleidoscope form. Uchiha Madara and his brother were the ones who awakened their own type of Mangekyou after the Sharingan. Amazon stocks non prescription colored contact lenses, and many cosplay costumes, but I did not find this type of lenses. Kuroni is a cosplayer from Prague, and her Instagram is filled with not only cosplay of anime characters, but also characters from different movies, games, and even one of the characters from the K-pop group KDA (League of Legends).
