Korea也是Colored contact lenses的生产集中地，G&G、NEO、MI、GEO四家是规模较大的生产工厂，向其他品牌提供代工。而目前G&G与MI自有品牌产出的镜片在中国缺少正规的引入途径，More是作为原材供应厂商，活跃在微商中的产品也很难保证其是否通过要求的医疗器械认证，所以不作为首选推荐。
 
NEO VISION is one of the largest contact companies in South Korea, with contact lenses accounting for up to 80% of the Korean eyewear market, and has repeatedly become the top seller in Japan and South Korea. NEO VISION's coloured lenses also use a sandwich structure, with the front and back layers made of P2-HEMA, and the middle layer infused with pigment for a more natural and long-lasting color. The small black ring series of visible eyes launched by it has a layer of solid color ring on the outer ring, but the color of the small black ring is not as strong as GEO, and the price of throwing a piece in half a year does not exceed 40 yuan.
 
NEO VISION is also a brand with many fakes, and you need to buy it through formal channels. It is worth noting that many micro-chambers of commerce advertise that their Korean color lenses are made of silicon hydrogel, and they are annual throwaways, but in fact, only Alcon and Taiwan's BenQ Merokang have really launched silicon hydrogel material color films, and at the same time, silicon hydrogel as a lipophilic material, the aging rate is much faster than that of hydrogel, Johnson & Johnson Anshiyou, Shikang and Cooper, the three major technologies have been very mature contact lens companies, and can only control the life of silicon hydrogel glasses to less than 30 days. Therefore, the so-called silicon hydrogel color film may still be an ordinary hydrogel product, and it is even more impossible to throw it away in half a year or a year, and you can't blindly listen to the propaganda and buy it.
