Yes, the majority of Pyramex safety glasses are treated with a special hard coating that will help prevent scratching. The polycarbonate materials that make up most safety spectacle lenses is naturally very soft, light weight and is excellent for absorbing the energy of an impact. However, the material can be easily scratched unless treated with a hard coating. You can assume that the Pyramex product you have selected will have this hard coating unless otherwise noted in the description as an uncoated product.
