Those Kardashians sure are unstoppable. They have a fragrance, a swimwear line, clothing line, shoe line, and jewelry collection. What's next?

The three reality TV stars' latest money-making venture is optical lenses.  The ladies released an ad for their new Kardashian Kollection eyewear for Sears. Victoria Beckham may now have some competition in the stylish frame department.

In the ad, the sisters wear black-and-white lace ensembles from their Sears collection. With their hair in a super high bouffant and their eyes framed with thick rimmed glasses, the Kardashian sisters make geeky look sexy. Khloe Kardashian-Odom poses in the center wearing a strapless bustier dress while her older sisters opt for a more conservative look. Kim Kardashian wears a fitted double-breasted blazer and Kourtney Kardashian wears a black top with a deep keyhole opening affixed with a gold bar paired with an open blazer with massive shoulder pads.

Khloe released the advertisement on her blog.

"Hey dolls. What do you think of this new pic of me and my sisters rocking Kardashian Kollection eyewear and some of our new lace items? I love it! I'm so excited about the launch of our new eyewear line -- be sure to check out all the styles in Sears Optical stores," she wrote.

Do you think the Kardashians know frames like they know fashion?
