Compared with contact lenses, cosmetic contact lenses have an extra layer of pigment in the middle that can change the color of the eyes. This also makes the oxygen permeability of cosmetic contact lenses worse. Therefore, the wearing time of cosmetic contact lenses should be shorter. It is recommended to wear them for 6 to 8 hours a day. Do not wear them every day of a week. Occasionally take a break for two days to relax your eyes, which can make them healthier to wear.

What are the types of colored contact lenses?

Colored contact lenses are divided into single color, double color, triple color, quadruple color and five color. The earliest colored contact lenses were monochrome series, which means there was only one color on the lenses. The most classic ones are black and chocolate. Later, manufacturers developed two-color, three-color, four-color, and five-color colored contact lenses, combining several colors into one lens to achieve a more gorgeous decorative effect. Nowadays, with the development of COSPLAY in China, a new series of colored contact lenses has emerged - art films. The colors include red, white, yellow and other bright colors to achieve the performance effect.
