Colored contact lenses, prized for their diverse hues and ability to make eyes appear larger and more beautiful, have gained popularity among beauty enthusiasts, particularly young women. However, as more people wear them, associated eye health issues have become increasingly prominent. Experts caution that behind this seemingly beautiful trend lies significant health risks. Below, we reveal the hidden dangers of colored contacts.
Experts explain that both colored and clear contact lenses are direct-contact lenses, meaning they come into direct contact with the cornea and conjunctiva. Any contact lens can cause mechanical damage through physical friction against these tissues. While clear lenses cause relatively minor damage, colored lenses have more pronounced texture due to added pigments, leading to more noticeable abrasion.Some unscrupulous manufacturers apply pigments directly to the lens surface during production. Beyond physical abrasion, this causes chemical damage. "We frequently find pigment particles shedding into the conjunctival sac of patients' eyes, potentially leading to keratitis or even corneal ulcers. In severe cases, corneal perforation may occur, causing catastrophic consequences for the eye,"" said Dr. Yin Lan, Associate Chief Physician at the Ophthalmology Department of the First Affiliated Hospital of the Chinese People's Liberation Army General Hospital. Dr. Zhang Hongbing, Chief Physician at the Ophthalmology Department of Xi'an First People's Hospital, added, "We generally advise against wearing contact lenses. No matter how thin or well-crafted they are, they remain foreign objects to the human body and will inevitably cause discomfort when worn."If wearing them is unavoidable due to work or special circumstances, we advise choosing simple, clear, standard lenses and limiting wear to 6-8 hours."
Zhang Hongbing recommends purchasing colored lenses only from licensed, reputable retailers.When selecting contact lenses, note that more elaborate designs pose greater risks to the eyes. For instance, colored cosmetic lenses often contain added pigments, have poor breathability, and can easily cause oxygen deprivation in the eyes. Remember: Simpler is better. Below is a brief overview of the hazards cosmetic lenses pose to the eyes: 1. Prolonged contact lens wear can easily lead to visual fatigue and even trigger dry eye syndrome.Symptoms include eye soreness, itching, a foreign body sensation, excessive discharge, dryness, burning, and blurred vision.
2. Prolonged contact with the cornea can numb nerve endings, reducing corneal sensitivity. Many patients develop ulcerative keratitis without noticing.
3. Colored lenses block oxygen from reaching the cornea, causing a condition similar to altitude sickness in humans. This impairs normal metabolic function and weakens the eye's defenses.
4. The chemicals in colored lenses can irritate the cornea, leading to inflammation and corneal damage.
3. Colored contact lenses block corneal oxygen exposure, causing eyes to experience oxygen deprivation similar to altitude sickness. This impairs normal metabolic function and weakens ocular resistance.
4. Colored contact lenses, often containing excessive chemicals, may cause eye redness and inflammation due to improper wearing habits, eye sensitivity, or weather conditions. Severe cases can lead to corneal hypoxia, deformation, infections, corneal perforation, and other serious eye diseases—potentially resulting in permanent blindness.
While women cherish beauty, protecting your eyes is paramount. Avoid counterfeit colored contacts that may cause irreversible damage—always purchase from reputable sources. Never wear them excessively long, and remember to clean lenses promptly.
Substandard colored contacts pose significant risks; exercise caution when using them.
The desire for beauty is universal.However, while pursuing beauty and trends, one must never overlook the quality of colored contacts. Surprisingly, 34.1% of netizens surveyed were unaware of the quality of their colored contacts. Additionally, 9.8% admitted to using substandard products, with some rationalizing that even low-quality lenses are affordable and fashionable—wearing them for a couple of days shouldn't cause harm.Such irresponsibility toward personal health is truly alarming.
Little do they realize that compared to regular contact lenses, substandard colored lenses pose far greater risks. Some low-quality lenses can permanently stain the cornea, while improperly disinfected lenses may spread diseases like trachoma or hepatitis B.Additionally, low-quality lenses can obstruct corneal oxygenation. Prolonged oxygen deprivation causes eye redness, swelling, pain, excessive tearing, and increased discharge. This creates conditions for bacterial infections, leading to ulcers, erosion, and in severe cases, corneal perforation or even eye necrosis.
