How to clean dirty contact lenses?
When we wear contact lenses, the eyes will constantly produce protein, lipid, inorganic salt and other secretions. Meanwhile, the dust suspended in the air and the impurities in the external environment will stick to the lenses. Contact lenses have the characteristics of spongy, and the precipitates are left on the surface of the lenses, resulting in the contact lenses getting dirtier and dirtier. Therefore, the lenses must be cleaned every time after wearing the contact lenses. So, how to do it?
After removing the contact lens, it must be cleaned with special care fluid. Contact lens care solution has the function of sterilization and disinfection. However, after the deposition of various dirt and impurities, it is not enough to wash and soak with the care solution alone. It must be rubbed with fingers. Place the lens in the palm of the left hand in several times, drip the nursing solution, rub the positive and negative sides with the index finger of the right hand, and pay attention to the direction from the middle to the surrounding. After cleaning, use small tweezers to hold up the lens, and use the flowing nursing solution to wash it thoroughly before putting it into the duplex box for soaking. This process may cost a lot of nursing fluid, but it is also a necessary process, and can not be reused.
However, no matter how perfect the maintenance method is, there will still be a small amount of stubborn dirt left on the lens. After a long time of use, the lenses gradually aged and deteriorated, and bacteria may grow on these deposits, which has become a huge threat to eye health. Therefore, contact lenses must be replaced in a timely manner. In case of any condition affecting wearing or eye grinding, the contact lenses should be discarded and replaced decisively.
Wearing contact lenses, health is the first important thing, more meticulous, more healthy.
