Abstract:
1. A device for applying a quantity of liquid to a lens, the lens having a predetermined convex curvature, the device comprising: a roller having: a top end; a bottom end; and an applicator surface defining an axis of rotational symmetry passing through both the top and bottom ends of the roller, wherein the applicator surface is concave and sized and shaped to be complementary in size and shape to the lens such that the predetermined convex curvature of the lens and the concave applicator surface have an equal radius; a wire, at least a portion of which is in contact with a portion of the applicator surface, wherein the wire is helically wound about the axis of rotational symmetry of the roller such that successive turns of the wire are in direct contact with one another and form grooves where the successive turns contact one another; and a computer numeric control machine attached to the roller, configured to control the application of the quantity of liquid from the roller to the lens.
