Essilor manufactures prescription corrective lenses for individuals with sight defects, non-prescriptive lenses sold at large retailers and pharmacies, and other instruments and equipment used in the optic industry, as of 2015. This latter group includes vision testing and measuring aids for industry professionals, precision optics machinery for prescription labs and other lens manufacturers, and a line of vision screening equipment for preventative healthcare institutions.
Essilor's prescription lenses have three components. The first is the design, or the aspect of the lens that corrects the sight problem. There is only one design per sight issue. The second component, the material, determines aesthetics, weight and resistance of the finished product. Finally, the coating offers additional functionality, such as anti-reflective properties and protection from the sun's harsh rays. Essilor's full selection of all of these components is available at Essilor.com.
Essilor's other products may not carry the Essilor name, but they remain products of the company. A company called FGX International is credited for some these products, but it is a wholly-owned subsidiary of Essilor. Non-prescriptive glasses carrying the brand names Foster Grant, Sight Station, Magnivision and Bolon are all FGX/Essilor products. Likewise, the company also produces glasses with the Disney, Reebok, Ironman, Body Glove and Field & Stream logos.
Satisloh, another subsidiary of Essilor, provides the equipment, tools, consumables and services needed for prescription labs and other lens to surface, coat and finish corrective lenses. Other Essilor brands include Varilux, Crizal, Definity, Xperio and Optifog. Taken together, Essilor Group products are available in over 100 countries.
