(Reuters) - Shares in Italy's Luxottica (LUX.MI), the world's biggest eyewear maker, fell for a second day on Tuesday on concerns for where it might be heading after the resignation of its second chief executive in as many months.


Shares in the maker of Ray-Ban and Oakley sunglasses fell an initial 5 percent and were still down 3.4 percent at 36 euros by 1015 GMT (0615 EDT), extending a 9 percent drop on Monday on news that CEO Enrico Cavatorta was quitting just six weeks after taking over from long-time boss Andrea Guerra.
Both Guerra and Cavatorta had clashed with 79-year old Luxottica founder Leonardo Del Vecchio, who in recent months has taken on a more prominent role at the company he controls via a 61 percent stake.
