The present invention is related to a method for making contact lenses with identifying mark, in particular to silicone hydrogel contact lenses. The present invention is also related to a method of high intensity UV curing the identifying mark print on the mold and high intensity UV treating mold for making silicone hydrogel contact lenses with identifying mark.

Contact lenses with identifying mark

The invention provide a method for cast-molding hydrogel contact lenses, especially silicone hydrogel contact lenses by using plastic molds of a poly(cycloalkylene-dialkylene terephthalate) copolymer. These plastic molds do not need to be degassed and stored in an oxygen-free atmosphere (e.g., Nor Ar) before being used for cast-molding silicone hydrogel contact lenses in the absence of oxygen and resultant silicone hydrogel lenses can still have relatively high ion permeability and relatively low variation in targeted optical power, compared with silicone hydrogel lenses made from a conventional mold material, such as polypropylene. The invention also provides plastic molds for cast-molding silicone hydrogel contact lenses.

Method for cast molding contact lenses

A container for storing a silicone hydrogel contact lens in a liquid, having a bowl portion with a radius such that the radius of the lens is from about 85 percent to about 100 percent of the inner surface radius. The bowl portion has an outer section which is defined by a radius larger than the inner surface radius. Furthermore, the bowl portion has a roughness sufficient to maintain capillary attraction of the lens to the bowl portion but preventing adhesion of any portion of the front surface of the lens to the bowl portion.
