Description

Contact lens colored pattern forming method and assembly thereof

The present invention relates to a contact lens colored pattern forming method and its assembly that can produce contact lens patterns. In particular, a contact lens colored pattern forming method and its assembly can customize contact lens patterns of various colors and patterns, even invisible The glasses pattern will not increase in thickness due to the amount of color.

Contact lenses are a type of lens that is worn on the cornea of the eye to correct vision or protect the eyes. Contact lenses do not have heavy frames and lenses, and are small in size, easy to carry, and do not affect the user's appearance. When contact lenses are worn on the cornea of the eye, the wearer will not feel any burden and will not affect the wearer's appearance. Therefore, since the advent of contact lenses, they have been loved by all walks of life, especially by young people and beauty-conscious people who use contact lenses to make up for their lack of vision.
