Luxury fashion brand Salvatore Ferragamo has extended its eyewear agreement with Marchon Eyewear for an additional five years.

The partnership, which was launched in 2012, includes sunglasses and optical frames for men and women.

"The increase in volume registered in the last three years, which has averaged just below 30 percent per annum, is confirmation of the incredible value of our partnership with Marchon," says Michele Norsa, chief executive officer, the Ferragamo Group.
