The main components of contact lens care solution are sodium chloride and preservatives, which are mainly used for cleaning, disinfection, and protein removal of biological materials. It is undoubtedly indispensable for people who wear contact lenses. However, some consumers reported adverse reactions such as eye redness and discomfort after wearing contact lenses. The main reason is that the wearer has some misunderstandings in the use of contact lens care solution. To this end, the health supervision agency reminds consumers that they must purchase and use contact lens care solutions correctly.


Pour on contact lenses, rub, soak

According to the relevant regulations of the "Disinfection Management Measures", contact lens care solution is a disinfection product, and the manufacturer must obtain the "Sanitary Product Manufacturing Enterprise Sanitation License" before production and sales, and the hygienic quality of the product can be guaranteed.

5. Method of use and scope of use;

6. Matters needing attention;

Secondly, you should see the function of contact lens care solution clearly when you buy it.

Folding why use care solution

The contact lens care solution is used by the contact lens family every day. The deposits and pathogenic bacteria on the lens surface must be removed with the care solution first, so that the subsequent sterilization and preservation can be carried out effectively. Because the surface of the lens is not completely cleaned, there will be residual deposits. When directly sterilizing, the sterilizing ingredients will only combine with the sediment, but not pathogenic bacteria. As a result, the sterilizing ingredients will not be able to play a bactericidal effect.

The correct way to fold and clean the lens

Studies have found that a complete and correct cleaning method can remove the deposits on the lens surface and kill 90% of pathogenic bacteria. However, in actual use, many users just do simple cleaning and do not rub it with their hands. Experts point out that this is very wrong. Because the most effective way to clean contact lenses by rubbing the lenses by hand is to use "your own hands", "lens cleaning solution", and "contact lens-specific, single-use saline solution". The correct method is to drop the lens cleaning drop on the lens, and rub the lens back and forth directly with the pulp of the finger. After rubbing, the lens should be rinsed repeatedly with normal saline, and finally, the lens should be fully moistened with normal saline. After this entire cleaning process is completed, sterilization can proceed.

  Steps for usage

1. Wash your hands with soap or hand lotion, and then remove the contact lenses. People who wear make-up should take out their mirrors before removing makeup, wash their hands first, then remove contact lenses, and then remove eye makeup.

2. Put the lens on the palm of your hand, drop a few drops of lens cleaning solution, put your finger against the lens, and use 20-30 seconds to gently scrub the lens back and forth in a straight line on the palm of your hand. (The circle-shaped scrub lens is easy to wear the lens.)

3. Rinse the lenses with "contact lens-specific, single-use" saline solution until the lenses are completely clean.

4. After making sure that the lenses are cleaned, use the "contact lens-specific, single-pack" physiological saline to fully moisturize the lenses. Follow-up sterilization storage can be carried out.

Contact lenses meet the requirements of many myopic patients for beauty and convenience, but some contact lens wearers have misunderstandings in their use. Damage to eyes. Some contact lens wearers are used to dripping the solution directly into their eyes, believing that it not only keeps the eyes moist, but also has a germicidal effect. In fact, instead of relieving symptoms, this behavior may cause certain eye diseases. Eye drops need to have a PH value (pH), osmotic pressure and ion concentration that are very close to physiological tears, and also contain antibiotics to achieve therapeutic effects without foreign body sensation in the eyes. And after the care drops into the eyes, not only can not eliminate eye bacteria, but also cause damage to the eyes. Nursing liquids contain preservatives, and dropping them into the eyes will destroy their physiological environment and cause eye diseases. In addition, although the care solution contains bactericidal ingredients, its effect is very weak. Long-term use will increase the drug resistance of some bacteria and delay the best treatment time for eye diseases.

How to choose a care solution? Provide four suggestions to consumers.

Rational view of function

In the Chinese market, almost all contact lens care solutions are multi-functional care solutions. The multi-functional care solution mentioned here refers to the independent care of the earliest steps of cleaning, cleaning, disinfection, lubrication, etc., which can be completed at one time. The most basic and most important needs of eyeglass care are the four functions of disinfection, cleaning, protein removal, and moisturizing. Products on the market, in addition to these basic functions, some products have added many other functions. Regarding the effects of various ingredients in the care solution, it is recommended to be based on science and rationally treated. Sometimes it can affect the efficacy of the basic ingredients, which can affect the care of the lens.

Choose mild and non-irritating

When buying a care solution, you should not only look at the bactericidal ability, but also whether it is mild and not irritating to the eyes. Some consumers have a misunderstanding and blindly believe that the stronger the bactericidal ability of the care solution, the better. It is recommended to maintain a certain balance, that is, while striving for sterilization, it is also gentle and non-irritating to the eyes. The non-irritating eye care solution will keep the eye cells in a healthy state, thereby contributing to the eye health of consumers.

Pay attention to the expiration date of the product

It is recommended that consumers pay attention to the production date of the product when choosing a care solution. Generally, the validity period of the care solution is two years after the production date, and once the bottle is opened, it is generally used within four months. At this time, it is necessary to pay attention to the validity period of the care solution at least greater than your use time. If the product is outside the expiration date, or the bottle is opened for too long, the disinfection ability of the product will decrease, which may affect eye health.

Don't just focus on no-rubbing

Consumers should go to regular optical shops or pharmacies to buy care solution. Before using the care solution, you should also read the instructions carefully, especially pay attention to the soaking time of the lenses, pay attention to eye hygiene and personal cleaning, and adhere to the correct lens wearing and care steps, so that you can enjoy the benefits of contact lenses healthily.

Many care solutions on the market are marked with the function of no rubbing. The concept of no rubbing is aimed at the function of sterilization. It does not mean that you can take off the glasses and put them in the mirror box directly. Instead, wash your hands first, take off the glasses and use them. The care solution is rinsed vigorously, put into the care solution lens case, shaken and soaked to complete the care process. Experts suggest that rubbing at the same time can remove the grease and protein attached to the lenses more obviously, especially for those who wear the lenses for a long time or use the lenses for a long time, it is more recommended to rub the lenses when caring for the lenses.
