It is because of this huge grey market in the unregulated sunglasses industry that it's difficult to point out the exact size of this market. But here are some indications of its large proportions. According to Harsh Chopra, managing director, Ray Ban Sun Optics India Limited, 3 to 4 lakh pieces (premium range, Rs 2,000+) get sold annually. Luxottica, the leading global eye wear company, has a Rs 40 crore business in India. Out of a total of 20 sunglass brands, it has successfully launched around nine of these like Ray Ban, Versace, Chanel and Bvlgari in India. Encouraged by the market response, in fact, this year they've launched yet two more brands, Prada and Arnette.
