ABSTRACT:
In opaquing and tinting a contact lens, an opaquing medium is deposited on the lens anterior surface as discrete randomly sized, randomly positioned droplets from a fine mist spray of the medium so that the ultimately formed opaque covering on the lens will correspond in appearance with the random droplet pattern. Mist spray apparatus also is provided.
