How often does the contact lens case change?
Everyone knows that the shelf life of contact lenses is the use cycle, the shelf life of the nursing solution is three months, but many people will not go to replace the contact lens case, they feel that the nursing solution into the disinfection effect, no longer need to replace the glasses case regularly.In fact, this idea is wrong. It's better to change the contact lens box every three months.
Contact lens box is very useful. Normally, contact lenses cannot be separated from the lens box. When you go out, you also need the lens box to carry and save the lens. But bacteria and fungi are everywhere. The cleaning of the eye box is directly related to the health of the lens, and more to the health of the eyes. In order to avoid increasing the risk of eye infection, not only the partner box, but also the small tools should be replaced together.
At the same time, like contact lenses, contact lens cases also need daily care. After each care of contact lenses, wash the lens cases with care solution, and replace the care solution in the case. If you don't wear contact lenses often, you should also change the care fluid every two days. In addition, at least once a week, the glasses box should be disinfected by boiling and scalding, and then exposed to the sun and dried to reduce bacterial growth.
At ordinary times, pay attention to tighten the cover of the duplex case to avoid the leakage of the nursing solution. Because of the nursing solution, the contact lens case itself is a relatively humid environment. Even if it is sterilized every day, it is difficult to prevent the growth of bacteria. Therefore, it must not be placed in the same humid environment as the bathroom.
The price of the contact lens case is actually not expensive, regular replacement will not increase too much economic burden, so in the purchase must pay attention to the choice of regular brand products.
