If it is health care, it is recommended to run Shiming (13.5 yuan).

Don't use eye drops indiscriminately. Eye drops have no health care function and are sometimes harmful.

The most healthy thing is your own tears. Normal tears contain a variety of nutrients and antibacterial components, which have the most suitable osmotic pressure and ideal pH value, and are natural eye protectors.

Many eye drops contain preservatives, which will cause direct damage to the eye surface.

Eye drops should also suit the remedy to the case

Modern people not only have wallets, keys and other necessities in their bags, but also have a bottle of eye drops, and the "eye drop aquarium" in the office is increasing day by day. Dr. Pan Zhiqiang, director of the eye bank of Beijing Tongren Hospital, said: "From the point of view of ophthalmologists, if there is no disease in the eyes, there is no need to use drugs."

Due to eye discomfort caused by dry eye and chronic conjunctivitis, people drop a few drops of eye drops from time to time. However, if you rely on eye drops or use them improperly, it will not only protect your eyes and treat diseases, but will do great harm to your eyes.

Use eye drops to treat the symptoms.

There are also many kinds of eye drops. Although many eye diseases have symptoms of redness, swelling and pain, the pathogenesis is different, so it is necessary to prescribe the right medicine when using eye drops. Before eye drops, check whether the drug name, concentration and expiration date are consistent with the packaging, whether there is turbidity or floc in the bottle, and whether there is discoloration. Dr. Pan listed several methods of using eye drops and matters needing attention for us.

The first category, antibiotic eye drops, anti-inflammatory eye drops, such as norfloxacin. It is the largest part of eye drops, which contain antibiotics and are used to treat eye infections. Abuse of this eye drop will destroy the bacterial ecology of the eyes. No eye drop can fight all infections, so you must use anti-inflammatory eye drops according to your doctor's advice.

The second category is eye drops for lowering intraocular pressure, that is, eye drops for treating glaucoma. There are many kinds of them, such as eye drops with mydriasis effect, which are all aimed at waterproofing. Therefore, eye drops for the treatment of glaucoma are not available to ordinary people and must be used in conjunction with corresponding diseases.

The third category, anti-cataract eye drops, such as piroxicam? Parked in the white hole, catherine? Snow, etc. , mainly used in the elderly or early cataract patients, normal people will not play much role.

The fourth category, pure lubrication, mainly brings moisture to the eyes and relieves discomfort. Such as artificial tears, eye surface lubricant, which is a polymer material with the function of polymerizing water, so it can keep the eye surface moist for two hours when put into the eye. There are about a dozen kinds on the market, some with preservatives and some without preservatives, which have no irritation to eyes at all. It is best to ask a doctor to choose his own situation.

The fifth category, hormone eye drops, contains corticosteroids, such as Belik. You must drop this medicine carefully. If you drop it four times a day, it will induce glaucoma for more than four weeks, and you can't randomly order it. Because there are hormones in it, it will induce hormonal glaucoma after use and the intraocular pressure will be very high. At this time, the medicine must be reduced, stopped or changed. Sometimes it is found that the visual function damage caused by the late stage is often irreversible and difficult to cure in the later stage. If the eyes are inflamed, antibiotics must be used at the same time.

6. Non-hormonal anti-inflammatory drugs (non-carrier drugs) are suitable for patients with uveitis and keratitis.

Four strokes to deal with four situations

For ordinary people, the most common thing is visual fatigue. If you feel sore eyes, you need eye drops to relieve them, but this should also be divided into reasons. Eye drops are not everything.

1. If you are nearsighted, but don't wear glasses, fatigue attacks are more frequent. You can use some eye drops, but from the doctor's point of view, it has little effect. Mainly because of eye muscle spasm, the eyes feel sore and uncomfortable. At this time, it is best to let your eyes have a rest, or wear glasses with the right degree to make your eyes comfortable and avoid the symptoms of eye fatigue. If the eyes are refractive, we should pay attention to eye care, rest and wear correct glasses to relieve eye discomfort.

2. Being in front of the screen for a long time, on the one hand, has the influence of radiation, on the other hand, because the eyes are staring at the screen, the number of blinks is reduced, and most people who work in front of the computer screen are in air-conditioned rooms, resulting in dry eyes and terminal syndrome. At this time, you can use some eye drops to moisturize your eyes, you can prescribe artificial tears in the hospital, and there are some over-the-counter drugs. The advantage of artificial tears is that they stay on the surface of eyes for a long time and can keep the surface moist for 2 to 4 hours. The eye drops of health care products will be gone in about 5 minutes. But some of these vitamins can also relieve eye discomfort caused by ciliary muscle spasm. It varies from person to person. If you still feel uncomfortable after stopping taking the medicine, you'd better see a doctor.

Some people's eyes are uncomfortable and dry because they have problems. In addition to refraction, there are recessive strabismus, especially recessive exotropia. Such patients are more tired than normal people. If they have strabismus eye drops, it won't solve the problem. It is recommended to go to the hospital for examination. Chronic conjunctivitis is an inflammatory reaction caused by the proliferation of some non-pathogenic bacteria in the eyes. Such people should pay attention to eye hygiene and develop good eye habits.

4. Eye infection caused by wearing contact lenses, or eye discomfort is caused by infection, because people have a habit of rubbing their eyes with their hands when their eyes are sore or uncomfortable. Sometimes the eye itself may have eye corner conjunctiva and cornea damage, and it will be infected with injured bacteria after being rubbed by hand. The patient suffers from some chronic conjunctivitis or related eye corner diseases. It's best to order some anti-inflammatory eye drops. But don't mess around, just order an anti-inflammatory eye drop, and choose ordinary eye drops, such as chloramphenicol and other eye drops that are not very effective. Remember not to use eye drops with strong antibacterial and anti-inflammatory effects. People who wear contact lenses must take off their glasses according to the glasses instructions. Don't wear glasses for too long at a time. If you feel eye discomfort, you can use some anti-inflammatory eye drops appropriately, or you can order other types of eye drops.

abuse

1. Tap water instead of eye drops

There are bacteria, fungi and a parasite called amoeba in tap water. In general, the problem is not serious, but if the epithelium of conjunctiva or cornea is defective, washing eyes with this tap water will induce infection, such as amoeba, and there is no particularly good drug treatment at present, and the final outcome is almost the confusion of the whole cornea and the loss of vision. Fungal infection can also cause fungal keratitis. It is not recommended to wash your eyes with tap water, or to drop tap water directly into your eyes, especially if your eyes are uncomfortable, often because of some trauma. If you wear contact lenses overnight, you won't take them off until the next morning. At this time, washing your eyes with water is the worst. You should drop some anti-inflammatory drugs and pay attention to your eye habits.

2. Frequent use of eye drops

If eye drops are used improperly, it will not only help the condition, but even bring a lot of future troubles. Some people only count eye drops once after they get an eye disease, thinking that as long as the dose is increased, the disease will recover as soon as possible. Actually, one drop at a time is enough. If used too frequently, the preservative in the liquid medicine will cause damage to the eyeball surface. Suspension eye drops should be shaken well before use. Some eye drops can be used at a fixed time to play their greatest role. Therefore, when to order eye drops, you'd better ask the doctor.

Eye drops are safe and harmless.

Some people think that one or two eye drops are safe and harmless, which is wrong. Improper use of some eye drops can lead to serious consequences. For example, long-term use of hormonal eye drops may lead to hormonal glaucoma and eventually lead to loss of visual function; Long-term use of antibiotic eye drops may induce non-pathogenic keratitis and conjunctivitis. Therefore, it is suggested that eye drops should be used under the guidance of an ophthalmologist if they are used because of eye diseases.
