Very Cheap Glasses from Prescription Glasses Online

Recently I found very cheap prescription glasses at http://www.prescriptionglassesonline.net/, only $5.95. At first I really can not believe, so I tried to have chat with their customer service, a girl called Lili is really an eye glasses expert, she not only has sexy voice, but also knows a lot on prescription glasses, I asked why they can offer so cheap eyeglasses, how can they make a profit. She told me because they are eyeglasses manufacturer, and they sell the eye glasses directly to customers, that's why they can sell at so low prices.
