Method and apparatus for marking coated ophthalmic substrates |
| abstract |
A method for marking an ophthalmic substrate or other ophthalmic article comprising the steps of -providing an ophthalmic substrate of suitable organic or mineral glass having opposed optical surfaces; -depositing a plurality of layers to define coatings on one or both of the opposed optical surface with anti-impact, anti-scratch, anti-reflection and/or anti- smudge properties, at least one of the layers being an electrically conductive layer; -providing a mask defining a configuration complementary to the desired marking for one of the surface of the coated ophthalmic substrate and positioning the mask in the immediate proximity of the ophthalmic substrate surface; and -providing an ion source and directing the ion beam from the ion source masked surface of the ophthalmic substrate to remove at least a portion of an outermost one of the coating layers exposed through the mask thereby producing a desired marking on the substrate surface coating rendered visible by fogging. |
