Care and cleaning for contact lens
The severity of eye disease is related to the cleanliness of the lens. Cleaning and maintenance is not processed well, not only reduce the service life of the lens, but also causeirreducibledamage to eye.
1. Should scrub lens by hand, just like the dirty clothes, if without scrub, and directly throw into the washing machine, then the stubborn dirt can not be removed. Contact lenses must be scrubbed by hand for more than 30 seconds, and then cleaning effectiveness can be achieved. Research report shows that scrubbing by hand is more efficiently to remove the impurities and precipitate on lens than any machine. In addition, there is no disinfection effect for running water or boiled water, so it can not be used to clean contact lenses.
2. Change the contact lenses for every 1 to 2 years. Any perfect way of cleaning can not ensure the totally removal of impurities and precipitate on lens. Even not for frequent use, after 1 or 2 years, the lens material will naturally become old, and this time should be discarded, so as not to damage the eyes.
3. Lenses can not be placed in normal saline, which dont have sterilization effect. If it is used to hold the lens, can easily be contaminated, and cause damage to eye.
4. Potion also has expired date. After sealed off, it is best to use up within 4 months or change for new ones, to avoid deterioration. The best using period for normal saline after sealed off is not more than 1 month since it is without preservatives.
5. Before wearing, contact lens should be washed by normal saline. Since potion for contact lenses is mostly chemicals, if wear directly will cause stimulation. So it is better to wash with normal saline before wearing.
6. Contact lenses can not be immersed in potion for a long time, since potion will lose disinfection capacity, and be restored into ordinary water, and become a hotbed for bacteria. Usually need to change the potion for every two days, but some potion can be storedwith sealing tightfor a week. This depends on composition of potion. Must be re-sterilized and washed before wearing again.
