Contact lens cabinet and practical can be carried, want to pick want to wear all by the mood, let a lot of people feel to meet each other late. However, the wrong contact lenses can cause a lot of damage to the eyes.
Contact lenses most taboo long wear, especially wearing sleep will cause serious consequences. The cornea breathes with the help of oxygen in the atmosphere and surrounding tissues, and sleeping lenses can severely impair the metabolism of the cornea, which in the long run can lead to new blood vessels. And when the new blood vessels grow to the center of the cornea, it can seriously affect vision.
In the process of wearing, eye secretions, impurities in the air and so on will adhere to the lens, and gradually form a precipitate. So, every time after taking off the lens, must be in strict accordance with the process to rub and wash and soak. Still, there are stubborn contaminants that can't be removed, and they get stuck in the oxygen holes, which not only affect the quality of the lenses, but also pose a potential threat to eye health.
In pursuit of higher oxygen permeability and comfort, contact lenses are becoming thinner and softer, so they are more likely to break, especially at the edges, where scratches or gouges will be left after pinching the lens. Such lenses, if worn consistently, may wear away corneal epithelial cells, making the cornea too thin to be operated on, and may cause serious consequences such as irregular deformation, shedding and even perforation of the cornea.
Beauty is important, but health is more important. While contact lenses themselves are harmless, it's important to remember to be aware of the risks associated with improper wear.
