Description of Related Art
Nowadays, concerning fashion or clothes matching, consumers begin to wear colored contact lenses capable of altering their natural iris color. However these different colored or patterned contact lenses would fade or discolor so as to make the wearers have ocular allergy.
A conventional colored contact lens is manufactured by forming a colored layer on the contact lens surface. However, when the consumer's finger touches the colored layer side during the process of wearing or cleaning contact lenses, the colored layer would easily peel from the contact lens surface. Therefore, the colorant in the colored layer is likely to fall off and to adhere on the surface of the wearer's eye so that the ocular allergy or infection of the wearer would occur.
Therefore, a colored contact lens having an excellent colored performance is highly demanded.
