Polaroid Eyewear has launched a contest for the 10 best sunglasses designs, which will be launched at the March 2013 Mido show in Milan. The designers will win a trip to the fair and will get royalties on the sale of the glasses. Their names will be mentioned in the description of the product. Sept. 30, 2011, is the closing date for participation in the contest. The winners will be announced at next year's Mido.
