Two decades ago, we saw a surge in blueberry eyesight products in Japan. The pioneer is Wakasa Seikatsu, which describes itself as a quality supplement company. Their main item is "Blueberry Eyesight" and you will see their product in pharmacies, convenience stores and groceries. You will also see the Blueberry Eyesight commercials on Japanese television around the clock.
Check out the Wakasa Seikatsu web page where you will see a whole collection of their clever commercials.
