Designers Dan and Dean Caten already dress celebrities -- including outfitting Britney Spears for many a tour date -- in their body-conscious looks and now the design duo is making the most necessary celebrity accessory: sunglasses.

At last night's launch event in a far west Chelsea warehouse in NYC, the designers were all smiles in trim tuxedo blazers.

"It's more straightforward and not too blingy, and it's also a bit masculine-y, so it can be unisex," Dean told StyleList of the new line.

While the design duo weren't inspired by any particular celebrity, they still had the famed hills in mind. "It's old Hollywood meets new Hollywood!" Dan added.

And the celebrities turned out in droves. Rachel Zoe confessed that Fashion Week was "fashionably exhausting" but still made it out for the red carpet.

Of the runway shows she's seen, the celebrity stylist/reality TV star loved Marc Jacobs, Derek Lam and on designers Kate and Laura Mulleavy, Zoe adds, "Rodarte almost made me cry it was so amazing."

Wearing head-to-toe DSquared, but accessorizing with a Goyard clutch, Hilary Duff sang the duo's praises. "DSquared is one of my favorite lines. I've always had a huge respect for designers for their vision and creativity. Maybe I'll get to be there someday. My line [with DKNY] is more for everyday, but it was still a little nerve-wracking."

Inside the two-story warehouse space there were models aplenty, including Tyson Beckford, making the rounds in the line's new shades.

But the roof was where it was at. With a view that included the Empire State Building, guests whiled the night away drinking champers and dancing to the live DJ. Only two more days to go for New York Fashion Week!

We're glad to see the label being so practical -- after all, sunglasses are one accessory that's good for you!

In the last year or two, it has become more common to see celebrities – usually the ladies, but I’m sure not exclusively so – suddenly appearing in public wearing eyeglasses. In particular celebrities who have never been seen in glasses frames in the past. This sudden myopic explosion could make us all think there is a healthcare timebomb in Tinsletown. Until we realise that these cunning celebrities are faking it! Wearing chunky-framed non prescription glasses – just clear non-correcting lenses – purely as a fashion statement.

According to Natalie Hormilla, Associate Editor at Fashionista.com, this viral trend began with Cate Blanchett, but rapidly spread to Helena Christensen, Daisy Lowe and Chloe Sevigny. And so for generations of common folk, the optical world has been turned upside down. Having endured the name-calling and teasing, and generally been labelled as a nerd and an outcast, we all eventually reach out to contact lenses or laser surgery for our salvation.

And then just as we start to enjoy our spectacleless new life, all of a sudden eyeglasses are cool. Well that’s just great! And these new cool geek chic non prescription glasses aren’t even subtle, semi-invisible, rimless glasses. They are the kind of specs Buddy Holly would have been proud of. And this all begs a single question: why?

There are a few reasons. People who wear eyeglasses are often perceived to be more intelligent than those who don’t. Totally baseless factually, but this is nevertheless a very common perception – I’m sure if we all dig deep, we can think of somebody who wears glasses and who is an imbecile!

For celebrities, it is important to get noticed and a pair of big chunky glasses should do the trick, especially if everybody already knows they don’t wear glasses. So in these cases, it’s really nothing more than a publicity stunt.

Away from celebrity for a while – since this trend has leaked into the mainstream – some people, especially professionals, wear non prescription fashionable glasses in order to be taken more seriously.

The other reasons for wearing fake glasses goes back to the ‘geek chic’ thing. Using them as an accessory, because they match the shoes or the bag, or the dog in the bag – hmmm, maybe somebody will come up with fashion specs for pooches. So in this case it’s simply a matter of coordinating the outfit.

But whatever your reason, maybe it’s time to dust off your old glasses and pop out the lenses, because geek is now chic, and the glasses are back.

So what's the verdict? feel free to post your comments here....while I go have my eyes checked
