Before Alcon was acquired by Novartis, it was the world's largest ophthalmic pharmaceutical company, and launched the first contact lens care solution without rubbing, OPTI FREE® EXPRESS®, which ® firmly occupies most of the global contact lens lens care solution market, while Shikang is the first brand to launch silicone hydrogel soft contact lenses, and the two were integrated and unified by Novartis into Alcon, and immediately rushed to the forefront of the contact lens industry, becoming the second manufacturer after Johnson & Johnson Vision, accounting for 25% market share.
 
However, the strong marriage also broke up, and Alcon officially spun off from Novartis in April 2019 and operated as an independent company. Alcon's current contact lenses are divided into three series: silicone hydrogel monthly disposable contact lenses AIR OPTIX, daily disposable contact lenses DAILIES, and colored contact lenses FreshLook.
 
In the general soft contact lens industry, although the use of highly oxygen-permeable silicone hydrogel is the mainstream trend, in the color contact lens, hydrogel is still the first choice, mainly because of the "honeycomb" structure of silicone hydrogel, although there are many "pathways" for oxygen to pass through, but at the same time, the possibility of pigment extravasation increases. Alcon can become the only brand among the four major brands to launch silicone hydrogel color contact lenses, firstly, because it is the first to master the patented technology of silicon hydrogel and is in a leading position in the industry, and secondly, it is also innovative in the process.®
 
The AIR OPTIX®COLO uses the first-generation silicone hydrogel lotrafilcon B, although the oxygen permeability reaches 138Dk/t, due to the addition of silicon, the lens becomes less hydrophilic, and the actual wearing experience will be more stiff and difficult. In other aspects, because AIR OPTIX®COLO is aimed at the needs of the European and American markets, the lens colors are relatively bright, and the Asian region has only selected three relatively natural flower patterns in Japan, plus two new brown colors, divided into AIR OPTIX® COLORS and AIR OPTIX® BRIGHT, two products as a two-week sale, but if you wear no makeup or light makeup, it will still be a little abrupt.
 
Fresh Look® is an ordinary hydrogel material, with a water content of 69%, the official blink moisturizing technology claims that every time you blink the spectacle lens will release a moisturizing agent, but in essence, it still adds moisturizing factors to the lens or solution, and the actual effect is unsatisfactory. But in terms of color and pattern, it is richer than Johnson & Johnson Anshiyou, there are gray, brown, green, blue, star brown, star black, star light brown 7 kinds of options, suitable for Asians to wear, 13.8mm small diameter is also more natural, 10 pieces of price is about 78 yuan, cost-effective, available on the online business platform.
