1. Be sure to rub the lens by hand.
Just like the general reason that dirty clothes can't be washed out by throwing them into the washing machine without scrubbing first, contact lenses must be scrubbed by hand for more than 30 seconds to achieve the cleaning effect. The research report points out that rubbing the lens by hand can remove impurities and deposits on the lens more effectively than any machine. In addition, tap water or boiled water has no cleaning and disinfection effect and should not be used to clean contact lenses.
2. Replace new contact lenses every 1 ~ 2 years.
No matter how perfect the cleaning and maintenance method is, there will still be a little microorganism left on the lens. Even if it is not used frequently, the lens material will naturally age after 1 ~ 2 years. At this time, it should be discarded and replaced to avoid eye injury.
3. The lenses should not be stored in normal saline.
Normal saline has no bactericidal effect, and is used to preserve lenses, which is easy to breed bacteria and cause eye infections.
4. Different brands of contact lenses cannot be used interactively.
Because different brands of potions have different types and components, do not mix or replace them at will, so as to avoid chemical action and damage the lenses. In fact, up to now, ophthalmologists believe that there is no contact lens potion without side effects.
Heating disinfection method will not cause the side effects of chemical residue, but heating method is easy to shorten the life of lens; The multifunctional liquid medicine is simple and convenient, and the dioxygen system has the strongest bactericidal power, but the cleaning function of the two systems is poor.
Although the traditional methods of cleaning, rinsing and soaking are troublesome, they are relatively safe cleaning and maintenance procedures for doctors at present.
5. Fixed deproteinization every week
Protein adsorbed on the lens will form a thick layer over time, which is easy to scratch the cornea. Deproteinization of enzyme tablets can decompose protein structure and keep the lens surface clean.
The ingredients contain enzymes, which can remove proteins. He believes that so far, there is still no disinfectant on the market that can completely replace the weekly deproteinization work.
In addition, the effect of deproteinized tablets is not better as long as they are soaked. Dr. Lin Siyuan explained that the soaking time should not exceed 12 hour, because the decomposed protein will re-penetrate into the lens and be firmly adsorbed, which will increase the difficulty of cleaning.
6. Potions also have a service life.
After the potion is unpacked, it is best to use it up or discard it for a new one within 4 months, so as to avoid deterioration of the potion. After unpacking, the service life of physiological saline solution should not exceed 1 month because it does not contain preservatives.
7. Before wearing contact lenses, rinse with normal saline.
Because invisible potions are mostly chemical preparations, it is easy to cause irritation when worn directly on the eyes. It is best to wash it with normal saline before wearing it.
8. Contact lenses should not be soaked in liquid medicine for a long time.
After being soaked for a long time, the liquid medicine loses its disinfection ability and returns to ordinary water, but becomes a hotbed of bacteria. Usually, a new soaking solution should be replaced every two days, but some potions can be sealed for a week, depending on the composition of the potions themselves. Be sure to disinfect and clean it before wearing it.
9. Send it to the original factory for maintenance once every six months.
Usually all glasses are washed together in the optical shop, which is easy to be infected. Individuals only need to do daily cleaning and maintenance, remove protein regularly every week, and only need to send it back to the original factory of contact lens company for maintenance once every six months.
10. The dioxide disinfection system must be neutralized before it can be used.
Because the dioxygen disinfection system uses 3% hydrogen peroxide (the same as that used in general trauma), it is necessary to use a white gold ring or a neutralization tablet to avoid burning eyes. For example, the neutralization effect of platinum ring will decrease with the increase of use times. It is recommended to replace the platinum ring at the same time every time you change the new potion. In addition, disposable contact lenses with high water content should not be disinfected by dioxygen system, and the lenses will be deformed.
1 1. If your eyes are red, you'd better take off your contact lenses first.
As long as the eyes are red, photophobia, tears and other discomfort, it is best to take off your contact lenses immediately and take them to see a doctor to see what the problem is. The cornea of contact lenses is usually fragile, and most people's vision is already quite damaged by the time their vision is blurred.
12. Replace the contact lens storage box regularly *-*
