The cornea, located in the front of the eyeball, is the first barrier to protect the eye from foreign bodies. The cornea itself is transparent and non-regenerative. When the corneal epithelium is damaged, bacteria and viruses enter the cornea and cause inflammation, which is a common form of corneal inflammation. In the process that everybody wears contact lens, lens should stick closely with cornea all the time, so how should prevent corneal infection again?
Generally speaking, lenses with water is the most likely to cause eye infections, so should never wear contact lenses to take a bath or sweat steam, nor use any liquid other than care solution to clean, soak contact lenses. Acanthamoeba is widespread in soil and water, and if it causes keratitis carelessly, it can lead to blindness in severe cases.
Sleeping with contact lenses can exacerbate the lack of oxygen in the cornea, leading to redness and swelling. Wearing contact lenses for a long time will hinder the cornea from obtaining oxygen from the air, and closing your eyes to sleep will further aggravate the corneal hypoxia phenomenon, if you are used to wearing contact lenses to sleep for a long time, the damage to your eyes is self-evident.
You should stop wearing contact lenses if you are not feeling well or if you have any problems with your eyes. People in the cold, fever, allergy and other periods, the body resistance is poor, eyes are more fragile than usual, easy to be invaded by bacteria and viruses.
Wear contact lenses in strict accordance with the correct procedures, not to pay attention to local hygiene will lead to corneal infection. Before handling the lenses, wash your hands carefully with soap and running water, and then dry them with a clean and hairless towel.
If you find eye inflammation, infection or other abnormal conditions, you should go to the hospital for professional examination in time. Do not buy and use eye drops by yourself, so as to avoid more serious consequences caused by delayed treatment.
