Innovation is Essilor’s top priority. The  group’s 550 researchers at our five Research & Development centres around the world have a double mission:
 - Anticipate the needs of glasses wearers, opticians and professionals
 - Propose innovating products to satisfy the demands of the optics market. 
 
Essilor strives to continually improve the performances and the quality of its products. To validate perfomance and quality levels, our researchers have developed a unique process whereby wearer’s perception is objectively measured through sensorial testing to further confirm scientific data.
