The company is rated as the most dangerous medical device lens or faded on the cornea
Colored contact lenses add beauty to the points, but its safety and health issues have not received enough attention. A few days ago, at the seminar on color contact lens health and safety experts sponsored by Johnson & Johnson Vision Health, many ophthalmologists stressed that the color contact lenses listed as Class III medical devices by the State Food and Drug Administration since June 1st are the highest risk. Graded medical devices. But now, the phenomenon of consumers buying colored contact lenses from informal channels is very prominent, and the security risks are great. The lens pigment is "printed" on the cornea Because the color contact lens contains a pigment layer and the diameter is larger than that of the transparent lens, it is more likely to cause eye complications. The clinical cases caused by improper purchase and wearing are not rare. Pan Qing, deputy director of ophthalmology at Zhejiang Provincial People's Hospital, shared a case published in the Korean eye journal KJO: a 30-year-old woman wears colored contact lenses for facial broad-spectrum pulsed light therapy (a cosmetic treatment similar to photorejuvenation) ), soon the eyes appeared discomfort, after removing the contact lenses, it was found that the lens pigment appeared almost entirely on the corneal surface. In the end, doctors can only use the scalpel to scrape the pigment on the cornea together with the corneal epithelium, and the patient suffers from great pain. Fortunately, the pigment does not adhere to the corneal epithelium, and the corneal epithelium heals itself within 72 hours. "In fact, I have heard that the glasses store has received complaints about the color faded in the glasses store. In the emergency department, the patient also claimed that the patient had taken off the color film and found that the dyeing pattern was incomplete. After inspection, it was found that there was a black-lined pigment attached to the eye. The inner surface of the watch is accompanied by inflammation of the conjunctiva." Pan Qing said that the purchase and improper wearing of colored contact lenses can cause a series of complications, including redness, corneal neovascularization, corneal abrasions and decreased sensitivity. Recently, the report of "Color Contact Lens Safety" jointly written by the Japan Ophthalmology Society and the Japan Contact Lens Association specifically pointed out that the problem of colored contact lenses, including the base curve or diameter of the lens, and the uneven thickness of the lens may affect the oxygen permeability. The surface of the lens is pigmented, and the surface and edges of the lens are not smooth. The phenomenon of informal channel purchase is outstanding Pan Qing analyzed the color contact lens pigmentation problem that consumers are worried about, which is related to the inlaying process of the lens pigment, the improper use of the wearer, the lack of oxygen in the eye contact lens, and the weakening of the cornea. Among them, the mosaic process of lens pigments is particularly noteworthy. At present, there are two main types of pigmentation on the color contact lens, one is surface coloring, that is, the pigment sheet is attached to the outer layer or the inner layer of the lens; the other is the interlayer embedding, that is, the pigment sheet is wrapped in two lenses. In the middle, commonly known as "sandwich". “If the pigment is not completely wrapped by the lens, it will increase the surface roughness of the lens, which will also lead to more bacterial microbial adhesion.†Xiao Xiaomei, a professor at the Eye, Laryngeal and Rhinology Hospital of Fudan University, reminded. In the opinion of experts, the “sandwich†process makes the pigment tablets not directly contact with the ocular surface, which is a safer process for the eyes, but the production cost is higher, and many companies may not be willing to adopt such high-priced processes. The strategy of “playing low-priced cards†is closely related to the current mentality of consumers dealing with colored contact lenses. In recent years, colored contact lenses with the "beauty" function have been highly sought after among Asian women. According to a Japanese survey, in 2012, there were 2.42 million women wearing colored contact lenses in Asia, including at least 1.2 million women in China. However, the industry estimates that there are more people actually using colored contact lenses. In fact, a large number of consumers buy such contact lenses from informal sources, including online purchases, and purchases of unlicensed or miscellaneous colored contact lenses from underground malls, beauty salons, and even street stalls. According to industry analysis, color contact lenses cause eye health damage frequently, because many wearers regard it as a small cosmetic, and do not particularly care about purchasing channels, and this mentality leads to serious medical risks.
