Hygiene is one of the most important factors in preventing infections and other problems. These problems not only affect your eye health, but also your long-term vision.

The following are some precautions for cleaning contact lenses and the reasons behind them.

How to clean contact lenses

Before touching contact lenses, be sure to wash your hands with soap and water.

Use antibacterial soap where possible, and dry your hands with a lint-free towel. Do not use oils or lotions, they will make your lenses cloudy or dirty.

Always use fresh contact lens cleaning solution.

Do not use tap or sterile water, saliva, saline solution or wetting drops. None of these can be used for disinfection and cleaning.

Be sure to rub the contact lenses with your fingers, and then rinse them with fresh cleaning fluid.

Studies have shown that “rubbing and rinsing” is the best way to clean contact lenses, even with “no rub” contact lens cleaners. Do not let your nails touch the lens. Not only are your nails sharp, they are also a great haven for bacteria and dirt.

Be sure to rinse the contact lens case with fresh potion, then turn it over and open it to dry.

Do not clean the case with water, because the water may contain impurities and microorganisms. In addition, do not put your box near the toilet or in a damp place, this will cause mold and bacteria to grow.

Other ways to keep contact lenses clean

  • Do not transfer contact lens solutions to a smaller container for travel or storage, as this may affect the sterility of the solutions.
  • Cap the potion bottle tightly and avoid touching the surface or object when using it.
  • Change the contact lens case at least every three months.
  • Do not wear contact lenses that are longer than the specified days after the first opening.
  • Avoid smoke and other pollutants in the air, which can enter your eyes and cause irritation and infection.


Always follow instructions

The instructions that come with contact lenses, contact lens cases, and contact lens cleaning solutions, as well as instructions from the ophthalmologist, are designed to provide you with the best care and performance for your specific wearing and cleaning environment.

In the end, your ophthalmologist is your ally in keeping your eyes and vision at their best. Talk to him or her every year to make sure your contact lenses and care system still fit your eyes and lifestyle.
