  • Method for spin coating a multifocal lens
    Patent number: 5753301
    Abstract: A method for coating a multifocal lens, lens blank, or lens mold is disclosed. The lens, lens blank, or mold is spun about an axis offset from the geometric center thereof. The lens, lens blank, or mold for the lens has at least two focal regions defined by at least one ledge line, and the axis of spinning passes perpendicularly through the ledge line or an extension thereof. A coating is applied during spinning, and spinning is continued until the coating is sufficiently dry that it has adhered with little risk of deformation to the coating on the lens, lens blank, or lens mold upon removal or movement. A lens produced by the method is also disclosed.
