Are foggy glasses getting in your way of seeing? Well now there is new technology to prevent this embarassing moment! Optifog lens has a special formula that you place on your lens once a week when you clean them and prevents your lens from becoming a foggy mess. I used to get the most complaints about foggy glasses and I am so glad Essilor has introduced their new Optifog product. Now when customers go from indoor to out door or vice versa their lens will not fog up! The Optifog lens is available for many prescriptions and lens options check with your Optical Center to see if they offer this spectacular lens.
