The correct use of eye drops What are the misunderstandings in the use of eye drops?

Many people often drop eye drops to relieve eye fatigue and improve the state of eyes. However, many people have some misunderstandings when using drugs, which is not conducive to eye health. So what are the misunderstandings in the use of eye drops? Let's take a closer look!

The correct way to read the instructions of eye drops Before taking the drug, you must read the instructions of the drug, know the name of the drug, make sure that you have used normal eye drops, and know the ingredients, usage, dosage, precautions, expiration date, side effects, contraindications, etc. If in doubt, you must not use it until you consult a doctor.

Pay attention to whether the eye drops have expired. Before taking the medicine, check whether the name, concentration and expiration date of the medicine are consistent with the packaging, whether the eye drops are turbid or flocculent, and whether there is discoloration.

If the eye drops have discoloration, odor, foreign matter and precipitation. , is the performance of deterioration, can never be used again. Check whether the eye drops change color and have impurities before each drop. Keep eye drops well to prevent pollution and deterioration.

Don't forget to wash your hands before taking medicine and eye drops to avoid hand contact infection; After dropping the eye drops, your fingers may touch the medicine or tears. You'd better wash your hands again.

When the head leans back and drops eye drops, the head should lean back or lie flat as far as possible. Pull down the lower eyelid with your index finger to separate it from the eyeball.

Aim at the eyes. Aim the bottle mouth of the eye drops at the eyes and at the conjunctival vault. One or two drops of eye drops are enough, and the eye ointment is about one centimeter long. Because the volume of eyeball surface is limited, tears are quickly discharged from nasolacrimal duct, so it is necessary to increase the contact time and time between eye drops and eyeball surface within this limited volume and time. Be careful not to touch the eyes or eyelashes at the mouth of the eye medicine bottle to prevent the medicine bottle from being polluted. Cover the bottle cap immediately after ordering the eye drops.

Press the inner corner of the eye and close your eyes for at least five minutes. Without blinking, gently press the nasolacrimal duct at the inner corner of the eye with your fingers for at least two minutes to slow down the discharge of liquid medicine.

Wipe the unabsorbed eye drops or tears around your eyes with a paper towel or handkerchief before opening your eyes.

If you need to order two or three kinds of eye drops at intervals, you need to order the second eye drops at intervals of five to ten minutes; If you need to order eye drops and eye ointment at the same time, you should order eye drops first, and then apply eye ointment every five minutes.

Common eye drops At present, there are three kinds of eye drops on the market, which are used to treat different types of eye diseases:

1, antibiotics, mainly used to treat eye infections, long-term abuse may lead to eye flora imbalance.

2, artificial tears, which is a substitute for imitating human tears, can moisturize the eyes and relieve dry eye. However, it should be noted that some products contain preservatives, and long-term use may damage the cornea.

3. Hormones have anti-inflammatory, anti-allergic and immunomodulatory effects. These eye drops can be used to relieve and treat dry eyes and allergies, but long-term use may lead to increased intraocular pressure, even optic nerve damage and decreased vision, leading to hormonal glaucoma.

Many people generally believe that eye drops are beneficial and harmless to the eyes, so they will be used as long as the eyes are uncomfortable, and they will become dependent on eye drops over time.

Misunderstanding of the use of eye drops Choose eye drops at will. Many people always think it's easier to use eye drops. Just choose one or two in the drugstore. Actually, there are many kinds of eye diseases and eye drops. For example, pinkeye can be conjunctivitis, keratitis, corneal ulcer, subconjunctival hemorrhage, acute iridocyclitis or acute glaucoma. In treatment, appropriate drugs should be selected according to different symptoms and causes. When eyes are uncomfortable, medication should be taken under the guidance of a doctor, and self-medication should be avoided to avoid serious consequences.

A few drops of eye drops at a time can increase the curative effect, and a variety of eye drops can be used at the same time. Because the volume of human conjunctival sac is obviously smaller than that of a drop of eye drops, one drop of medicine can achieve the therapeutic purpose once. Too many drops will not increase the therapeutic effect, but will be wasted. The interval between dropping two kinds of eye drops should be at least 5 minutes, and it is not advisable to use them at the same time.

Frequent use of eye drops In recent years, the incidence of dry eye has increased, which is not only related to air pollution and the use of refrigeration and air conditioning, but also one of the important reasons for its onset. At present, only one or two prescription eye drops or over-the-counter eye drops contain no preservatives. Preservatives can damage conjunctival goblet cells, and long-term use may induce dry eye.

People who use eye drops or use computers for long-term close work have symptoms of asthenopia or chronic conjunctivitis after working for a certain period of time, that is, they are treated with antibiotic eye drops, which is a misunderstanding in treatment. Because long-term unreasonable eye use is often the root cause of the above discomfort, not caused by infections such as bacteria and viruses. Only scientific and rational use of eyes and daily attention to eye hygiene are the most fundamental prevention and treatment methods. At this time, you can use some eye drops to relieve the symptoms.

It is fundamentally wrong to think that one or two drops of eye drops are completely safe and harmless when using eye drops. Long-term use of eye drops will not only cause the above dry eye, but also lead to hormonal glaucoma, non-pathogenic keratitis, conjunctivitis and so on. Even allergic reactions caused by some components in the liquid medicine are life-threatening. If eye drops are used to treat eye diseases, they must be used under the guidance of an ophthalmologist.

Store eye drops at will. After several drops of eye drops, the eye drops will be put somewhere. After a few months, my eyes were uncomfortable again, so I found eye drops and used them casually. In fact, it is wrong to do so. Any medicine has an expiration date, and the expiration date of eye drops is shortened to one month after the first use. In addition, eye drops cannot be stored at will. It is wrong to put eye drops in your clothes pocket or on a table with strong light for a long time. Eye drops should be kept in a cool place. If possible, they can be kept in a refrigerator at 4℃. Pay attention to the shelf life of eye drops.
