摘要:
A method of forming a removable protective coating on a hydrophobic surface of an ophthalmic lens element, including the method: providing an ophthalmic lens element having a hydrophobic surface, the hydrophobic surface being formed by coating at least a part of a surface of the element of lens with a hydrophobic coating; applying a non-aqueous coating composition in order to coat at least part of the hydrophobic surface, said composition including a film-coating polymer and a compatible non-aqueous solvent; and removing a substantial portion of the solvent from the composition to form a removable protective coating on the ophthalmic lens element that adheres to the hydrophobic surface; wherein the hydrophobic coating and the removable protective coating provide that (i) the protective coating is a detachable film that can be removed from the hydrophobic coating by physically detaching the removable protective coating from the hydrophobic coating or (ii) the protective coating is a water-soluble film that It can be removed from the hydrophobic coating by washing the removable protective coating with water, characterized in that the film-coating polymer is selected from the list consisting of styrene polymers, cellulose polymers, poly (meth) acrylate polymers, poly ( vinyl acetate), polyvinylphenol, polyvinylpyrrolidone and polyvinylpyrrolidone-co-vinyl acetate.Un método para formar un revestimiento protector retirable sobre una superficie hidrófoba de un elemento de lente oftálmica, incluyendo el método: proporcionar un elemento de lente oftálmica que tiene una superficie hidrófoba, formándose la superficie hidrófoba revistiendo al menos una parte de una superficie del elemento de lente con un revestimiento hidrófobo; aplicar una composición de revestimiento no acuosa a fin de revestir al menos parte de la superficie hidrófoba, incluyendo dicha composición un polímero de revestimiento peliculígeno y un disolvente no acuoso compatible; y retirar una porción sustancia
