Be careful not to "damage your pupils" when wearing colored contact lenses for manicures! Ophthalmologists warn against the risks of colored contact lenses

Nowadays, nail art and colored contact lenses are favored by many beauty lovers. Although nail art and colored contact lenses seem to make people more beautiful, there are also hidden risks. Xiao Li (pseudonym), a 20-year-old college student, is a "colored contact lens addict". She has myopia of about 600 degrees and does not wear frame glasses, but wears colored contact lenses every day. However, she has had serious problems with her eyes in the past few days.

Recently, Xiao Li attended a friend's wedding. She wanted to visit the city after attending the wedding, but when she set out, her right eye became red, painful, photophobic, tearful, and she couldn't wear cosmetic contact lenses. But she didn't cancel the trip. Because of the long journey, Xiao Li also caught a cold and had a fever. For the sake of beauty, she still wore cosmetic contact lenses in her left eye. It was very inconvenient to see the world with one eye.

"Doctor, will this white spot on my eyeball affect my vision in the future?" Xiao Li asked the ophthalmologist at the ophthalmology hospital worriedly when he went to see a doctor. After the doctor's examination, he found that Xiao Li's right eye had ciliary congestion, mild corneal edema, and a round gray-white turbidity in the center of the cornea. He was diagnosed with a corneal ulcer in the right eye. At the same time, the doctor also found that Xiao Li had beautiful but long and sharp nails on both hands. After detailed questioning, it was found that the patient's nails may have touched the black eyeball when removing the contact lenses a few days before the onset of the disease, and this is very likely the cause of Xiao Li's illness this time. After the consultation, the outpatient doctor gave a specific diagnosis and treatment plan, and Xiao Li is currently receiving active treatment.

The ophthalmologist said: "Currently, young women are more likely to get manicures, but they need to pay attention to hand and eye hygiene and safety issues. When sharp nails come into contact with the cornea, it can scratch the cornea at the least, or cause corneal perforation at the worst. The former can be repaired with treatment, but the latter will leave a scar on the cornea that is difficult to disappear even after recovery. Fortunately, Xiao Li sought medical treatment in time. If corneal ulcers are not treated promptly and actively, it is easy to cause corneal perforation, which can lead to decreased vision or even blindness in severe cases."

People who love beauty should pay attention: Are cosmetic contact lenses safe?

In real life, many girls like to wear colored contact lenses, which not only enhance the exquisiteness of makeup but also can be used as contact lenses. But are colored contact lenses really safe?

It is understood that cosmetic contact lenses are a type of colored contact lenses that were first invented to help people with eye injuries cover up blemishes, and have gradually evolved into a type of fashionable glasses. Cosmetic contact lenses are generally made of polyhydroxyethyl methacrylate as a matrix, with other hydrophilic soft lens excipients added, and then pigments or paints added for eye beauty. [1] In 2014, the State Food and Drug Administration issued a relevant announcement, clearly stipulating that decorative colored flat contact lenses that directly contact the cornea should be managed as Class III medical devices with a higher risk category. Their production and operation must obtain a production and operation license. [2]

Experts warn of health risks of cosmetic contact lenses

Ophthalmologists say: cosmetic contact lenses are meant to come into direct contact with the eyeball. Some low-quality cosmetic contact lenses have pigments directly applied to the lenses. Soaking and rubbing the lenses during daily care may cause the colored film layer to gradually fall off, resulting in direct contact of the pigment with the ocular surface, causing conjunctivitis, corneal epithelial defects or allergic reactions. Wearing cosmetic contact lenses with poor oxygen permeability will hinder the contact between the cornea and the air, affecting the breathing of the cornea, leading to corneal hypoxia and conjunctival congestion, and even corneal neovascularization. If the material of the cosmetic contact lenses is harder, it may wear the cornea. It is also possible that due to inadequate cleaning or prolonged wearing, too much protein may be deposited on the surface of the cosmetic contact lenses, causing corneal epithelial damage. When the lenses are not clean, the wearing habits are bad, or the body's resistance is reduced, infection may occur, and wearing cosmetic contact lenses for a long time may also cause a variety of ocular surface inflammations.
