Abstract
The invention provide a method for applying a coating to an ophthalmic lens or a mold for making the ophthalmic lens or a medical device other than ophthalmic lens. The method comprises spraying at least one layer of a coating liquid onto an ophthalmic lens using a spraying process selected from the group consisting of an air-assisted atomization and dispensing process, an ultrasonic-assisted atomization and dispensing process, a piezoelectric assisted atomization and dispensing process, an electro-mechanical jet printing process, a piezo-electric jet printing process, a piezo-electric with hydrostatic pressure jet printing process, and a thermal jet printing process. The coating can comprise a property/functionality pattern or a color image or combination of both.
