SAN FRANCISCO—E-commerce eyewear site DITTO has announced $5.0 million in additional funding from August Capital and strategic partner, National Vision, Inc. An earlier seed round led by August Capital brings the total funding raised by Ditto to $8 million.

DITTO also announced yesterday a partnership with National Vision, Inc., the fourth largest optical retailer in the U.S. and operator of America’s Best, Eyeglass World and Vision Center inside select Walmart stores. DITTO will be licensing its patented virtual try-on technology and experimenting with in-store kiosks at America’s Best locations for a test to begin in 2015.

DITTO.com is a site that allows consumers to record a short video of their face from their smartphone or webcam to create a 3D virtual self, or “DITTO.” Users can virtually try-on designer prescription glasses and designer sunglasses in 180-degree views to see how a particular style looks and fits their face before they make a purchase. DITTO has been issued two patents thus far.

“By incorporating personal style preferences, facial measurements and face shape into our recommendation algorithms, we’re giving customers the confidence they need to buy eyewear online,” says Kate Doerksen, cofounder and CEO of DITTO.

In addition, DITTO has launched a unique style and fit quiz that customizes a Personal Shop of eyewear for each customer.

DITTO was cofounded by Doerksen while she was in business school at Stanford, and Sergey Surkov and Dmitry Kornilov who were previously engineers at Google and Nokia, respectively. DITTO is venture backed by August Capital, National Vision, Inc, S:Cubed Capital and Broadway Angels.
