At the beginning of March, a 21-year-old girl in Wuhan matched her contact lenses. She thought it was too troublesome to take them everyday, so she was too lazy to take them off again. Unexpectedly, five months later, the right eye suddenly disappeared. Inspection found that contact lenses and cornea grow together, cornea was bitten out of a mung bean size hole, completely blind.
Precautions for wearing contact lenses
1. Do not wear contact lenses when washing or bathing. Contact lenses and related products should be stored away from light.
2. Never wear long nails when wearing contact lenses. Long fingernails are easy to leave external bacteria. When you take off your glasses, they will damage the lenses and eyeballs. In addition, the lens box should be thoroughly cleaned once a week with care solution. To protect your eyes, don't wear contact lenses for more than 8 hours a day.
3. The eyes are red. It's better to take off the contact lenses first. As long as the eyes are red, photophobia, tears and other discomfort, it is best to take off the contact lenses immediately, and take the contact lenses together to the doctor for examination, to see what is wrong. The cornea of the contact lens family is usually fragile. Most people come to see a doctor when their vision is blurred. At this time, their vision has been quite damaged.
4. Generally, the nursing solution will be used up within 3 months after opening. In summer, the use time shall be shortened, and it shall be discarded after expiration to prevent bacteria breeding. No matter what kind of nursing solution is used, it shall be scrubbed carefully every day after removing the mirror.
5. Wear contact lenses to make up. The method is to wear glasses before make-up and take off the glasses before removing make-up. Try to choose cream type cosmetics and light make-up.
6. Make sure to wash the lens by hand. Just like the principle that dirty clothes can't be removed without first scrubbing and directly thrown into the washing machine, contact lenses must be hand scrubbed for more than 30 seconds to achieve cleaning effect. According to the research report, washing the lens by hand is more effective than any machine in removing impurities and precipitates on the lens. In addition, tap water or boiled water does not have the function of cleaning and disinfection and cannot be used to clean contact lenses.
7. Replace new contact lenses every 1-2 years. In the perfect way of cleaning and maintenance, there will still be a little microorganism left on the lens. Even if it is not often used, the lens material will naturally become old after 1-2 years. At this time, it should be discarded and replaced to avoid eye injury.
8. Lenses shall not be stored in physiological salt water. Physiological salt water has no bactericidal effect. It is used to preserve the lens, which is easy to breed bacteria and cause eye infection.
9. Contact lenses shall not be immersed in liquid medicine for a long time. After a long time of immersion, the liquid medicine loses the ability of disinfection and becomes ordinary water, instead, it becomes a hotbed of bacteria. Generally, a new soaking solution should be changed once every two days, but some liquid medicines can be sealed for a week, depending on the composition of the liquid medicine itself. Before wearing, it must be disinfected and cleaned again.
