The Essilor Sun Solution is a new range of plano and prescription sun lenses produced in partnership by BNL and Intercast. Both are leading players in the sun lens market that belong to the Essilor group. There are five main categories of lenses – Sport & Performance, Protection, Fashion & Lifestyle, Vision and Prescription. The choice of the best solution is based on the specific needs of the client. The lenses may be made with NXT, polycarbonate, CR-39 or nylon, in traditional or customized colors. The specifications may include additional enhancements: they may be photochromic or polarized, with melanin or Vision* technology. The latter has built-in light management technology that improves the wearer's perception of color. Some of the lenses in the range are made in Italy for the collections of fashion brands, in trendy colors and coatings that enhance the aesthetic effect.
