Glasses should not only be selected correctly, but also maintained properly

Maintain according to the instructions of the medicine. The key points of each bottle of maintenance solution are different, and there may not be a difference in quality. In fact, correct maintenance can achieve the same cleaning effect. Use according to the instructions of each brand. For example, hydrogen peroxide solution needs to be soaked for at least 6 hours, while general multifunctional maintenance solutions are best rubbed and cleaned before being maintained for 4 hours to take effect. In addition, it is important to pay attention to the manufacturing date and shelf life of the maintenance fluid, and avoid using expired solutions. Even if the maintenance solution is not used up within three months after opening, it should be discarded and it is best not to continue using it.
★ Regularly replace contact lenses, including hard contact lenses for long-term wear, which should also be updated every 1-2 years. In addition, do not mistake daily throwing for bi weekly throwing or bi weekly throwing for monthly throwing. Extending the usage period on your own can harm the cornea.
★ Fixed protein removal. If using hydrogen peroxide solution, it is necessary to remove the protein before soaking the solution every day; For those who use multifunctional maintenance solution, it is recommended to regularly remove protein every week to reduce the chance of infection.
★ The lenses should not be stored in physiological saline solution. Physiological saline solution has no bactericidal effect and is used to preserve lenses, which can easily lead to bacterial growth.
The storage box should be cleaned at least once a week and replaced regularly every three months to avoid becoming a breeding ground for bacteria. The cleaning method can be to dip a cotton ball in cleaning solution, wipe the inside of the small box, then disinfect it with hot water above 79 ℃ and air dry it. Try not to put it in the bathroom as it is prone to mold growth due to humidity.
Do not immerse the lenses in the solution for a long time, as the solution will gradually lose its disinfectant function and become a breeding ground for bacteria. It is best to change the immersion solution of contact lenses every 2 days if they are not worn frequently, and remember to disinfect and clean them again before wearing them.
When swimming, never wear contact lenses. Chlorine, bacteria, impurities, and other substances in the swimming pool can adhere to contact lenses, causing damage to corneal tissue or infection, and even corneal ulcers.
If you want to change the medicine due to seeing a new product on the market or a friend's introduction, you must pay special attention to the condition of the new medicine after use, such as redness, itching, foreign body sensation, dryness, tears, secretions, etc. You must stop wearing it and confirm that it is an eye or medicine problem. If the medication causes it, it is recommended to stop using it and switch back to the original medication.
