How to use contact lens care solution correctly? Specification for use of contact lens care solution

Contact lens care solution is a necessary product for using contact lenses. All non daily throwing contact lenses must be soaked in contact lens care solution every day. Although everyone who wears contact lenses will use nursing solution, only correct operation can thoroughly clean the lens and remove protein. So how to use contact lenses correctly? This article brings you the correct use specification of contact lens care solution. Let's have a look.

1. Correct use of contact lens care solution

First, wash your hands and dry them carefully to ensure that the contact lenses are not polluted by tap water.

Then drop the nursing liquid. Put the lens on the palm of your left hand (or right hand) and drop 3 drops of fresh contact lens care solution on the contact lens.

Rub again. The right (or left) index finger dispersedly rubs the lens from the center of the lens to the edge for 10 seconds to thoroughly clean the edge of the lens. Relevant experiments show that rubbing and cleaning contact lenses for 30 seconds a day can reduce the probability of corneal infection. Rubbing the lens by hand can remove impurities and sediments more effectively than any machine and nursing solution.

Then rinse. Comprehensive washing is also essential. Wash both sides of the lens with sufficient nursing solution for 5 seconds to remove all residues on the lens.

The last is soaking. After fully cleaning the contact lens, soak it in the storage box and rest for at least 4 hours to ensure that the nursing solution has the functions of disinfection, cleaning, automatic deproteinization and soothing lens adjustment. In order to achieve 100% deproteinization and effectively alleviate eye diseases, it also needs the help of a special deproteinization contact lens reduction instrument. The lens should be completely immersed in the nursing solution, and the box cover must be tightened.

2. Use up as soon as possible after opening

In addition to choosing a suitable contact lens care solution, you should also pay attention to the use time of the care solution. Generally speaking, the shelf life of contact lens care solution is long, and the production date and shelf life are printed on the package. However, after the cover is opened for use, the shelf life of contact lens care solution will be greatly shortened. Usually, a bottle of nursing solution should be used within three months after opening. However, some products are marked to be discarded 4 or 6 months after opening. If there are adverse reactions such as redness and itching in the eyes during use, stop use immediately and go to a regular medical institution for examination.

In addition, the nursing solution should be placed in a dry place. Keep the bottle cap tightly closed when not in use, and do not touch anything to avoid bacteria from entering the bottle.

If you don't wear contact lenses every day, you need to change the nursing solution soaking the lenses frequently. If the nursing solution is not replaced for a long time, it will lose its cleaning ability. Generally, the nursing solution should be replaced once every 1-2 days.

3. Nursing liquid cannot be used as eye drops

In life, some contact lens wearers are used to dropping nursing liquid directly into their eyes. They believe that this can not only keep their eyes moist, but also have bactericidal effect. In this regard, experts remind that nursing liquid must not be used as eye drops.

Eye drops need to have pH value (PH), osmotic pressure and ion concentration very close to physiological tears, and contain antibiotics, so as to achieve the therapeutic effect without foreign body feeling in the eyes. Contact lens care solution is mainly used to clean and disinfect lenses. Most of its components are sodium chloride and preservatives. After dropping into the eyes, it can not only eliminate eye bacteria, but also cause damage to the eyes. In serious cases, it can induce dry eye disease.

In addition, although the nursing 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 of eye diseases. If you suffer from eye diseases, you must go to a regular medical place for diagnosis, and the unauthorized use of eye drops or contact lens care solution will only aggravate the condition and delay the treatment of the condition.

Contact lens care solution also has shelf life and correct use methods. Only the correct methods can ensure eye health.
