There are Cool Shades and there are Sinister Shades. There are Nerd Glasses and there are Meganekko Glasses. And then there are these.
Perhaps it's the bright pink lenses. Perhaps it's the rhinestone-encrusted frames. Perhaps it's the way they jut out several feet from the wearer's face. Whatever it is these glasses have, the one thing they do not have is subtlety.
These glasses come in a mix-and-match variety of styles, depending on the effect the costume department is going for:
Kamina's shades aren't even the most spectacular ones. They get topped about twenty episodes later with Simon's Kamina/Kittan homage shades. And this all ignoring the ones some of the mecha wear.
Little known fact: Squirtle was wearing the pointed shades a good decade before Kamina ever donned them.
Calvin wore shades that were remarkably similar to Kamina's in a Sunday strip of Calvin and Hobbes, predating both Gurren Lagann and Pokémon by quite a bit.
Togano Shozo of Eyeshield 21 sports a pair of oversized, orange-tinted sunglasses that somehow manage to escape notice or mention throughout the entirety of the series thus far.
During his first few appearances (before getting a more consistent design), jerk jock Agon sported cheetah print framed shades. Apparently, everyone in this series is oblivious to silly sunglasses.
Comic Books
Spider Jerusalem of Transmetropolitan. One lens red, the other green. One lens round, the other square.
Peter Fox sports a similar pair of shades, which every member of his family hates to his relief: "Finally, a pair of shades no one wants to borrow."
As mentioned above, Calvin once tried to get his mother to buy him a pair of sunglasses that were apparently picked up by Kamina years later.
Film
The heart-shaped sunglasses from the Stanley Kubrick version of Lolita.
The heart-shaped glasses never appear in the movie itself; only in publicity material.
In Terminator 3, Arnold ends up stealing his usual all-black & leather outfit from a gay male stripper and tries on a pair of gaudy star-shaped sunglasses that he finds in the pocket. He then takes them off and steps on them as he walks off.
The shades occasionally worn by Ray Person in Generation Kill are themselves mild compared to the other examples here, but become quite silly when worn by a US Marine in fatigues/MOPP gear invading Iraq while explaining the finer points of life in the Corps ("We pimpin'") or hitting on hot Iraqi women. It was enough for Person plus his shades to be the miniseries' cover◊.
Live Action Television
The Saturday Night Live sketches "Coffee Talk with Linda Richman" has Linda Richman (Mike Myers) wearing outrageously large tinted glasses.
In Twin Peaks, the lenses of Dr. Jacoby's glasses have different colors.
In Quantum Leap, Al occasionally wears a pair of red, lightning-bolt-shaped shades.
The vicar wears a big, glittery red pair that says "BOOB" (with the lenses as the 'o's) in The Vicar of Dibley, during the episode where they're expecting Elton John to open the Dibley village fair.
Geraldine:(sees herself in the mirror as she goes to answer the door)Well, obviously not!(takes them off)
John Conlee. Like Damon Gant and Porter C Powell, listed above he also has a pair of pink glasses (actually rose colored but close enough), the glasses actually appear on the covers for 3 of his albums (album pictures can be viewed by clicking on above link)
Axl Rose wears pink glasses in the video for "November Rain".
Real Life
Pictured above: Sir Reginald Kenneth Dwight aka Elton John is famous for these, and they appear in every parody of him. See many of them here
Curiously, he doesn't use them so much now. He had some of his most famous pairs auctioned for charity purposes, so he tends to stick to Cool Shades.
Dame Edna's glasses, with glitter stars hanging from the corners.
Paul Shaffer... just... Paul Shaffer.
While not as gaudy as most examples, UK snooker player Dennis Taylor was noted for wearing outsized glasses. Apparently this served a purpose - he wasn't looking over them when lining up his shot. (These days virtually all professionals opt for contacts or laser surgery, although glasses are one of the few optional items that are actually permitted by the very strict snooker dress code.)
Anaglyph 3D glasses, aka "those shades with the red and blue / green lenses." Not very many people wear them as a fashion statement, but those who do are probably going for this trope.
Video Games
Miror B's ridiculous star-shaped sunglasses in the Pokémon Colosseum games definitely apply.
Travis Touchdown from No More Heroes wears a variety of coloured shades... his default one are 'Sunflower Yellow', but they're also available in Peony Pink, Cobalt Blue, Pumking Seed Orange, and - if you're feeling particularly boring - traditional grey.
Academician Prokhor Zakharov from Alpha Centauri wears boat-light glasses. As literally as possible-one lens is red, the other is green (except their directions are reversed: his glasses are red on the right and green on the left, whereas a boat is the other way around).
Tabitha, the recurring guest on the Black Mountain Radio broadcast in Fallout: New Vegas wears pink, heart-shaped glasses with one lens missing, and a blonde babydoll wig with a red ribbon (referred to as her "truth-seeing eye" and "head of real hair"). Seeing as Tabitha is a hulking, overmuscled, blue-skinned supermutant with few definite sexual characteristics and the voice of a longtime smoker gargling gravel, it might be a desperate attempt to hold on to any vestiges of feminine identity. Being terminally insane plays some part, as well.
Web Comics
Helen B. Narbon is almost never seen without her little pink glasses. Well, except when she was turning into Dave.
Homestuck has several characters with sunglasses that are combined with phones/PDAs. Even before this upgrade, there are still characters in 3D-colored shades, red cats-eye lenses, and black Kamina/Squirtle shades.
Web Original
Lee Phillips from KateModern is very fond of bizarre sunglasses. His favourite pair are pink, with guitar-shaped frames.
