The invention is directed to a colored contact lens designed for making a wearer's eyes to appear larger, bolder, and enhanced color while giving the wearers eyes a very natural appearance. A colored contact lens of the invention comprising a first print of a first color and a second print of a second color, wherein the first print consisting of an annular ring of gradient dot matrix, wherein the second print comprises a limbal ring and an outer starburst pattern, wherein the limbal ring surrounds the outer starburst pattern, wherein the annular ring and the limbal ring have a substantially identical outer diameter and the annular ring has a larger inside diameter than the limbal ring, the first color and the second color are different or the same, wherein the first print and the second print are concentric with the center of contact lens.

The present invention relates to a hand-held fluorescence photometer and method for measuring an analyte level, preferably a blood glucose level, from an ocular fluid. The photometer is based on a dual beams measuring system and it is capable of defining the correct positioning for the measurement. Only when the apparatus is correctly positioned the actual analyte measurement automatically takes place.

Apparatus for measuring an analyte concentration from an ocular fluid

A method comprises the steps of (a) providing a water based ink in at least one clich&#xe9; with a contact lens pattern; (b) transferring the water based ink from the clich&#xe9; to at least a surface of at least a contact lens forming mold by means of at least a transfer pad; (c) at least partially curing the ink transferred on the mold to form a colored film; (d) dispensing a hydrogel lens-forming material into a lens-forming cavity of the mold; and (e) curing the lens-forming material within the lens-forming cavity to form the contact lens, whereby the colored film detaches from the molding surface and becomes integral with the body of the contact lens; characterized in that the relative air humidity in the immediate vicinities of the transfer pad/s is kept higher than 50% at standard temperature and pressure conditions during ink transfer.
