'Teashades' (sometimes also called "John Lennon glasses" or "Ozzy Glasses", after Ozzy Osbourne) were a type of psychedelic art wire-rim sunglasses that were often worn, usually for purely aesthetic reasons, by members of the 1960s drug counterculture, as well as by opponents of segregation. Rock stars such as Mick Jagger, Roger Daltrey, John Lennon, Jerry Garcia, Liam Gallagher and Ozzy Osbourne, all wore teashades. The original teashade design was made up of medium-sized, perfectly round lenses, supported by pads on the bridge of the nose and a thin wire frame. When teashades became popular in the late 1960s, they were often elaborated: lenses were elaborately colored, mirrored, and degregated, produced in excessively large sizes, and with the wire earpieces exaggerated. A uniquely-colored or darkened glass lens was usually preferred. Modern versions tend to have plastic lenses, as do many other sunglasses. Teashades are hard to find in shops today; however, they can still be found at many costume websites and in some countries.
The term has now fallen into disuse, although references can still be found in literature of the time. 'Teashades' was also used to describe glasses worn to hide the effects of marijuana (conjunctival injection) or 'bloodshot' eyes or the effects of opiates such as heroin (pupillary constriction).
The glasses worn by Seraph in the Matrix films are teashades. Teashades are briefly referenced during a police training seminar in Hunter S. Thompson's novel Fear and Loathing in Las Vegas. Anime characters Ban Mido (GetBackers) and Basara Nekki (Macross 7) are almost never seen without their purple-lensed teashades. Vash the Stampede (Trigun) wears yellow-lens teashades. Main character of Hellsing, Alucard, wears red-lensed teashades. Recently, actress and fashion icon Mary-Kate Olsen and pop music singer Lady Gaga have been seen wearing several variations of teashades. Howard Stern was also known for wearing teashades in the early to mid 90's and never taking them off in public.
