Beschreibung
Zusammenfassung:	A contact lens 10 comprises a non-opaque pupil region 40, a generally annular-shaped iris region 30 circumferentially surrounding the pupil region, and a pattern 20 printed on the iris region and extending across a portion of the iris region to impart at least a perception of a structure of an iris of an eye. The diameter of the iris region is greater than the diameter of the iris 50 of a wearer, thereby making the eye of the wearer appear bigger when the contact lens is worn. Preferably, the diameter of the pupil region is greater than the diameter of the pupil 70 of a wearer. The printed pattern may be a single colour, and that colour may be the same as that of the iris of the wearer.
