What are the risks of frequently wearing colored contact lenses?
All colored contacts pose risks to the eyes; avoiding them is best. Frequent use carries several hazards:
1. Corneal staining
Many manufacturers cut costs by using 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 may cause corneal staining.
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 environmental factors.
4. 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. Inability 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 Standards
The quality of colored contacts sold on the market varies widely. Some retailers source products through unclear channels, and secondhand lenses may even circulate. Since these lenses lack prescription strength and serve primarily decorative purposes, they aren't subject to the same stringent market access regulations as eyeglasses. Furthermore, there are no specific penalties for retailers caught selling secondhand lenses.
3. Lack of Disinfection Procedures
Beyond quality disparities, many retailers fail to implement rigorous disinfection protocols when providing trial lenses to customers, leading to bacterial transmission and potential infections.
Precautions for Wearing Colored Contact Lenses
1. If you must wear colored contacts, first disinfect and clean them thoroughly. Before insertion, wash your hands meticulously under running water with soap at least twice.
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 if eye discomfort persists to ensure 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 optician.
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. This can damage the cornea and lead to eye conditions.
Note: Colored lenses are widely available, but avoid purchasing them from small shops where quality cannot be guaranteed. It's best to buy them from reputable optical stores, checking the quality, manufacturer, and carefully reading the instructions.
