Although eye drops are topical preparations, but if used improperly can easily cause adverse consequences. In fact, we usually use eye drops there are really a lot of misconceptions. Myth 1: eye discomfort on the use of eye drops Long-term close work or use of computers, after working for a certain period of time, visual fatigue or chronic conjunctivitis symptoms, the use of antibiotic eye drops treatment, which is a misconception in the treatment. This is because long-term unreasonable eye use is often the root cause of the above discomfort, not due to bacteria, viruses and other infections. Only scientific and reasonable use of the eyes, daily attention to eye hygiene is the most fundamental method of prevention and treatment, at this time can be appropriate drops of some anti-fatigue eye drops to relieve symptoms. Myth two: eye drops can be used frequently for a long time In recent years, the incidence of dry eye disease increased, in addition to air pollution and the use of refrigeration and air conditioning, in addition to the long-term frequent use of eye drops is also one of the important causes of its onset. At present, regardless of prescription eye drops or non-prescription eye drops, only one or two do not contain preservative ingredients, preservatives have a damaging effect on the conjunctival cupped cells, long-term use may induce dry eye disease. Myth 3: It is absolutely safe to use eye drops The idea that one or two drops of eye drops are completely safe and harmless is simply wrong. Long-term use of eye drops can cause dry eye disease as mentioned above, but can also lead to hormonal glaucoma, non-pathogenic keratitis, conjunctivitis, and even life-threatening allergic reactions due to certain ingredients in the solution. If you use eye medication for a certain eye disease, be sure to use it under the guidance of an ophthalmologist. Myth #4: Random selection of eye drops Many people always think that eye medication is relatively simple, to the drugstore to choose one or two on their own. In fact, there are many types of eye diseases and eye medications, such as red eye can be conjunctivitis, but also keratitis, corneal ulcers, subconjunctival hemorrhage, acute iridocyclitis, or acute glaucoma. The treatment should be based on the different symptoms and causes to choose the appropriate medication. When eye discomfort occurs, medication should be used under the guidance of a physician, and never self-medicate to avoid serious consequences. Myth 5: You can use a variety of eye drops at the same time Because the volume of the human conjunctival sac is significantly less than the volume of a drop of eye drops, therefore, a drop of drops can be used to achieve the purpose of treatment, more than one point will not increase the therapeutic effect, but rather waste. The interval between the two eye drops should be at least 5 minutes, and should not be used at the same time. Myth 6: Store eye drops at will Eye drops are good after a few times, so they will be placed somewhere at hand. After a few months, eye discomfort, find out the eye drops and use them at hand, this is not right. Any drug has an expiration date, and the expiration date of eye medication is shortened to half a month after the first use. In addition, eye medication should not be stored at random. It is not right to keep eye drops in your clothes pocket or on a table with strong light for a long time. Eye drops should be kept airtight in a cool place, or in a 4°C refrigerator if available, and the shelf life of eye drops should be noted.
