Kim, Khloé and Kourtney Kardashian hawk new eyewear in bizarre ad

Attention, Sears shoppers! Kim, Khloé and Kourtney have another product to add to your overflowing Kardashian Kollection basket: eyeglasses.

In their latest ad, posted on Khloé's blog, the trio model their new spectacles while clad in a headache-inducing explosion of print, part of their new KK lace line.

It's unclear what kind of pose the sisters are trying to strike here -- nerd chic? studiously sexy? -- but all we see is uneasiness and confusion.

Then again, maybe we just need glasses. Where, oh where, can we buy a pair?
