Zoe Saldana is fronting a new advertising campaign for LensCrafters.

The 'Avatar' actress is working with the optical brand on their new 'My Look' service, which offers customers the chance to try on four frames and take high-definition pictures with each, comparing the images side-by-side.

In a backstage video for the photoshoot, Zoe said: ''I think it's very important to have glasses that sort of reflect or enhance your character.

''I have the sexy ones, the studious ones ... [and being] the girl that I am, I'm also looking for the Jackie Os, or the Audrey Hepburn sort of look.''

The adverts will debut today (01.11.12), in print, online and in over 900 LensCrafters stores throughout the US.

As well as enjoying having fun trying new frame styles, Zoe previously admitted she enjoys experimenting with her looks on the red carpet.

Zoe said of her stylist: ''She's one of my closest friends and we have so much fun with fashion. I don't let it worry me.''

Zoe has a huge interest on fashion and loves admiring dresses designers have made.

She said: ''I love the craftsmanship of it ... I love the composition, what designers go through to build a collection, to build a line, to build a label, a brand.''
