Bausch & Lomb is a pathfinder in China's contact lens market, entering Chinese mainland in 1987 and once sought after by consumers. However, the old club changed hands, and five or three recalls, which greatly damaged Bausch Lomb's vitality. With the rise of a new generation of consumer groups and the frequent exposure of quality problems by Bausch & Lomb, Bausch & Lomb's first-mover advantage has gradually disappeared, ranking last among the world's four major contact lens companies.
 
Bausch & Lomb lags behind other brands in terms of material, and only the PureVision series of silicone hydrogels used, and only monthly products, and the four series of Bio true, SoftLens, air, and ProfVision still adhere to the hydrogel material.
 
Bausch & Lomb's PureVision Day & Night Lunar Polishing Material is the same first-generation silicon hydrogel as the old PureVision Day & Night Lunar Polish, and since the patents were owned by Seecon at the time, part of the proceeds were used to pay royalties to PureVision. In order to solve the problem of lens hydrophobicity, both Shikang and Bausch & Lomb have adopted "surface treatment technology", and the "lamination" technology used by Shikang is better than Bausch & Lomb's oxidized hydrophilic layer technology, resulting in the use experience of pure vision is not as good as that of Shikang day and night, the oxygen permeability is only 91DK/t, the moisture retention, lubrication, and surface smoothness are poor, and the advantage is that the protein deposition is relatively small during the replacement cycle, and the price of 6 pieces of about 200 yuan is not high.
 
Later, the PureVision2 second-generation silicone hydrogel was launched, which is one of the more outstanding products of Bausch & Lomb, with various indices improved compared to the first generation, the thickness has been reduced, and the oxygen permeability has increased to 130Dk/t. Although the hardness is still high, the moisturizer, lubrication and surface smoothness have been significantly improved, and the wearing comfort is not bad, and the price of 3 pieces is about 149 yuan.
 
In order to compete in the high-end market, Bausch & Lomb has launched a "super hydrogel" biomimetic Bioture Bole pure daily polishing, with a very high water content of 78% and an oxygen permeability coefficient of 42DK/t, but the essence is still a traditional hydrogel, but there is an ingredient in the material that can form a layer of oil layer on the surface of the lens to lock in moisture, just like the tear film oil layer of the human eye, so as to achieve the purpose of moisturizing, in addition to the high water content, THE CENTER THICKNESS OF THE LENS IS 0.10MM, WHICH IS ON THE THICKER SIDE. In terms of comfort and moisturizing technology, this daily disposable is outstanding among Bausch & Lomb products, and there is not much difference between it and its rivals Johnson & Johnson or Alcon, but the price of 10 tablets of 103 yuan is relatively expensive, and there is no obvious advantage compared with the daily disposable silicon hydrogel at the same price on the market.
 
Among the four major brands, it is not difficult to find that Johnson & Johnson Anshiyou, Alcon, and CooperOptics currently have almost no long-wearing lenses above the half-year level, only Bausch & Lomb has launched, but it is also placed in the secondary line, and the annual wear lenses use hydrogel, although the molding is good, the water content is low, and it is friendly to the first wearer, but this kind of lens has poor oxygen permeability, and long-term use is easy to produce lens scratches and protein deposition. The ProfVision series is not recommended.
