Colored contacts can make eyes appear larger. Just look at actresses like Tang Yan wearing them in period dramas to see their popularity. But what are the risks of frequent use? Below we outline the dangers of regular colored contact lens wear.What are the risks of frequent colored contact lens use? All colored lenses pose risks to the eyes, and avoiding them altogether is best. Frequent use carries several dangers:
1. Corneal staining: To cut costs, some manufacturers use only two layers of film instead of the standard three. They apply dye directly to the inner lens layer and bake it dry. Prolonged wear can cause the dye to stain the cornea.
2. Eye redness and inflammation: Wearing colored contact lenses, especially those with excessive chemical additives, can cause eye redness and inflammation due to poor wearing habits, eye sensitivity, or weather conditions.
3. Permanent blindness: Prolonged contact lens wear may lead to corneal hypoxia, deformation, and eye infections, causing severe conditions like corneal perforation and potentially resulting in permanent blindness.
4. Risk of corneal inflammation: Users of contact lenses and colored lenses may experience varying degrees of corneal inflammation, as these lenses interfere with normal corneal metabolism and tear production.
What are the risks of colored contact lenses?
1. Eyes may fail to adapt. Colored lenses block corneal oxygen exposure, impairing metabolic function and reducing resistance. Even premium brands pose risks, as no lens—regardless of high oxygen permeability or water content—fully meets the eye's physiological needs.
2. Varied Quality: The quality of colored contacts sold on the market varies widely. Some retailers have unclear sourcing channels, and secondhand contacts may even be mixed in. However, because colored contacts lack "prescription strength" and serve only a decorative purpose, they are not subject to the same strict market access regulations and oversight as eyeglasses. Furthermore, even if retailers are found selling secondhand contacts, there are no relevant "penalty" provisions.
3. Lack of Disinfection Procedures: Beyond quality issues, many retailers fail to follow strict disinfection protocols when providing trial lenses, leading to bacterial transmission and potential infections.
Precautions for Wearing Colored Contact Lenses
1. If wearing colored lenses is necessary, always disinfect and clean them thoroughly beforehand. Wash hands meticulously with soap under running water at least twice before handling.
2. Exercise extreme caution during insertion and removal to prevent injury to the eyeball or cornea.
3. If discomfort occurs after wearing, remove the lenses immediately. Consult a professional ophthalmologist for examination if eye discomfort persists, ensuring no underlying eye conditions exist before wearing.
4. If your eyes feel dry after wearing them, do not use your regular eye drops. Purchase contact lens-specific eye drops from an optical store.
5. Do not wear your contact lenses immediately after purchase. Soak them in the prescribed solution for four hours first.
6. Trim your nails if they are too long to prevent scratching the lenses.
7. Since colored lenses adhere closely to the eye, avoid rubbing your eyes while wearing them to prevent corneal damage and eye diseases. Note that colored lenses are widely available, but avoid purchasing them from small shops where quality cannot be guaranteed.
It's best to buy colored lenses from reputable optical stores, checking their quality, manufacturer, and carefully reading the usage instructions.
