"Contact lenses" is actually a registered trademark dedicated to Johnson & Johnson ACUVUE, and only contact lenses with beauty effects launched by Johnson & Johnson ACUVUE can be called "contact lenses", but with the market influence of the product in China, "contact lenses" has become synonymous with color contact lenses to a certain extent.
 
As the first company among the world's four major contact lens manufacturers to launch contact lenses with cosmetic effects, Johnson & Johnson has created a "sandwich" process based on the materials and mature technology of ordinary soft contact lenses, which sandwiches the color layer between the glasses, and the pigment does not extravasate into contact with the cornea, which has also become the mainstream process of color lens manufacturing. At present, Johnson & Johnson has factories in the United States and Ireland, and the vast majority of its products are manufactured in Irish factories.
 
Generally, the shorter the use cycle of contact lenses, the higher the safety, the oxygen permeability of annual lenses is poor, and long-term wear is easy to deposit protein to breed bacteria, so the products of the three major brands of Johnson & Johnson Vision, Seekang, and Cooper are basically only daily, biweekly and monthly, and Johnson & Johnson's color lenses only include daily and biweekly treatment.
 
Johnson & Johnson Vision uses the hydrophilic etafilcon A hydrogel material to make the daily color lenses, which are soft and have a small foreign body feeling, and the water content reaches 55%, because the water of the lenses with high water content is easy to evaporate, and Johnson & Johnson Vision uses the Dangjia LACREON® hydrocoagulation technology to use the hydrophilic polymer compound PVP as the moisturizing factor, which is embedded into the lens through the outer coated treatment to ensure the comfort of long-term wear.
 
Astigmatism within 100 degrees can also be worn daily lenses, the colors can be selected are gray gold, caramel coffee, black, gray and brown 5 kinds, the pattern imitates the iris texture design, the eye effect is natural, suitable for daily wear, the price of a box of 5 pieces is about 48 yuan, the tear design of the packaging is very intimate, a tear is broken, will not easily pull to the connected packaging to cause waste,
 
Johnson & Johnson's biweekly color lenses are slightly inferior, the same material as the daily throw, the water content of the lens reaches 58% but does not use moisturizing technology, the wearing feeling is not as comfortable as the daily color film, the pattern is only brown Yanyan, 8.3 base arc for most Asian eyeballs to adapt to the 8.4-8.6 base arc, it seems too small, the slide problem caused by many people criticized, the price of 6 pieces is about 123 yuan.
