  • Edging process of lens using transparent coating layer for protecting lens
    Patent number: 9134461
    Abstract: The present invention relates to a process of edging a lens comprising forming a lens-protective transparent coating layer on the surface of the lens. When the lens coated with a transparent coating layer comprising a fluorine-containing elastomer and optionally a fluorine-containing organosilane compound and having a surface energy of less than 15 mJ/m2 is edged, the scratch of lens during handling, the damage of lens caused by chemical contaminants, and lens off-centring phenomena can be prevented. Further, such an edging process requires no adhesive tape, making the process simple, and prevents the contamination of the lens surface. Further, the inventive transparent coating layer makes it possible to measure the diopter of lens exactly owing to its transparency and it is manually removable without a chemical.
