Many people like to wear contact lenses, but do you clean your contact lens cases carefully? What the eye-loving girl wants to tell you is, "If you don't change your contact lens case for half a year, there will be more than 100,000 bacteria around!" Have you ever thought that a contact lens case can also become a weapon that "hurts and destroys your eyes"? This is no joke, otherwise the consequences will be serious...

The experts tested the bacterial counts in four contact lens cases, one of which had been used for one week, two for three months, and one for half a year. The results showed that the glasses case that had been used for one week had 500 bacterial colonies, while the glasses case that had been used for three months and six months had more than 100,000 colonies!

Experts say that tens of thousands of colonies are enough to cause eye infections. Even if the contact lenses are cleaned very well, it would be useless if they are placed in such a glasses case.

How often should you change your contact lens case?

Contact lens cases are used every day as storage boxes for contact lenses. They are essential care tools for contact lens users. Because they need to contain care solution, they are often damp, which is a potential source of infection.

If the contact lens case is kept damp and unclean for a long time, it can easily lead to the growth of bacteria such as Pseudomonas aeruginosa, thereby contaminating the lenses. It can also easily cause itchy, red and swollen eyes and other discomforts after wearing, affecting eye health.

Generally speaking, contact lens cases should be replaced every 2 to 3 months, cleaned with a neutral detergent every day, and placed in a ventilated, dry place.

In addition, it is worth noting that if contact lenses are not worn temporarily, they should be cleaned and disinfected and stored in a contact lens case filled with contact lens care solution or sterile saline to prevent lens contamination and drying, but the lens case should also be cleaned and handled in time. At the same time, for the sake of hygiene, it is best not to place contact lens cases in humid places such as bathrooms where mold and bacteria may grow.
