Teruhiro Ueno has seen both his business and reputation grow by upholding a key retail strategy: undercutting the competition.

The 67-year-old founder of the Zoff eyeglasses chain has thus taken on the handle of "price-breaker" in the process of revolutionizing the cost of retail glasses.

Starting with just one outlet in Tokyo, Ueno now has 81 nationwide and sells about 1 million pairs of glasses annually. And he's looking to go global.
