In the competition of soft contact lens industry, Alcon is leading with silicone hydrogel in terms of material, and Johnson & Johnson is a leader in the moisturizing process.
 
CooperOptics' lenses are made by dry casting molds, known for their large luminosity range and full cylindrical axis, and its entire series can provide -20.00D~ 15.00D non-customized ordinary lenses, which are very friendly to people with high myopia, and have also won the title of Best Astigmatism Contact Lens in the 2015 Eye Vote Readers' Choice Awards. In addition, all lenses are designed with a low edge, which gradually thins from the center to the edge, making it easier for first-time wearers to distinguish the front and back of the lenses, and the wearing is more suitable for the eyeball, and the foreign body sensation is weak, but it takes a little time to remove it.
 
CooperOptical's soft contact lens product line is divided by material, and in terms of silicon hydrogel, it has clariti clear oxygen and Biofinity. The traditional hydrogels include Proclear, Mediflex, Biomedics, and Oacry.
 
Clariti 1 day was originally the world's second similar daily disposable product launched by Safulong after Johnson & Johnson Anshiyou launched the first silicon hydrogel TruEye constant oxygen, while the iron is hot, after Cooper's acquisition of Safuron, it has become Cooper's product series, and is currently sold in China under the name of "Qingyang Qing", using the third-generation silicone hydrogel somofilcon A material, 86DK/t oxygen permeability is in the middle, and the unique WetLoc™ simulates the natural distribution of the tear film of healthy eyes. The moisture is evenly distributed throughout the lens from the inside to the outside, and the moisturizing temperature is much better than Cooper's hydrogel products, but compared with Johnson & Johnson Anshiyou, due to the different lens forms, there is still a gap in comfort, as the first generation of products, the current price is low, and the price of 30 pieces is about 119 yuan.
 
Biofinity also uses the third generation of silicon hydrogel, the material monomer itself is hydrophilic, can maintain the balance of oxygen permeability coefficient and water content, with Aquaform moisturizing technology, low water loss rate, oxygen permeability coefficient compared with clear oxygen clear increased to 160Dk/t, long-term wear moisturizing good, but protein deposition will be more, need to be rubbed and cleaned frequently during the use cycle, 3 pieces are priced at 139 yuan.
 
Cooper also offers a variety of traditional hydrogel products, including proclear, which is made of Omafilcon A, which has been approved by the US FDA as hydrogel lenses for patients with mild to moderate dry eye disease. The water content is as high as 60%, thanks to the powerful biofilm PC moisturizing technology, the eye diving feeling is not obvious after long-term wear, and it has more than 1000 power lenses, which performs very well in traditional hydrogel products, and the price of 30 pieces is 159 yuan. The Ocufilcon hydrogel material they use is the fourth type of hydrogel material designated by the FDA, which is a high-water ionic polymer with weak precipitation resistance, so it is mostly a short-cycle daily disposable product, and the price of several 30 pieces is about 90 yuan. In view of the decline of traditional hydrogel lenses, it is still more recommended to buy silicone hydrogel products with higher comfort and oxygen permeability.
