How to clean contact lenses? How to clean contact lenses

Contact lenses require correct cleaning methods to achieve thorough and effective disinfection and sterilization. You can rub the lenses with your hands, and please note that contact lenses cannot be used for a long time. Generally, new contact lenses need to be replaced every 1 to 2 years.

1. Be sure to wash the lenses by hand

Just like if you throw dirty clothes directly into the washing machine without scrubbing them first, you will not be able to remove stubborn dirt. Similarly, contact lenses must be scrubbed by hand for more than 30 seconds to achieve the cleaning effect. Research reports indicate that hand-cleaning of lenses is more effective than any machine in removing impurities and deposits from lenses. In addition, tap water or boiled water do not have a cleaning or disinfecting effect and cannot be used to clean contact lenses.

2. Replace your contact lenses every 1 to 2 years

No matter how perfect the cleaning and maintenance methods are, there will still be some microorganisms remaining on the lenses. Even if you don't use it often, the lens material will naturally become old after 1 to 2 years. At this time, you should discard it and replace it with a new one to avoid damaging your eyes.

3. The lenses cannot be stored in saline solution.

Physiological saline solution has no bactericidal effect. If used to store lenses, it can easily breed bacteria and cause eye infections.

4. Contact lenses of different brands cannot be used interchangeably

Because different brands of solutions have different types and ingredients, they cannot be mixed or replaced at will to avoid chemical reactions that may damage the lenses. In fact, so far, ophthalmologists believe that there is no contact lens solution that is completely free of side effects.

The heating disinfection method will not cause the side effect of chemical residues, but the heating method can easily reduce the life of the lens; the multi-functional solution is simple and convenient, and the dual oxygen system has the strongest bactericidal power, but the cleaning function of the two is poor.
