4hw.com.cn: we often feel dry and tired eyes in our work and study. Eyedrops can help us relieve eye fatigue. Recently, it was reported that eyedrops directly drop on the eyes and destroy the eyes. How can eyedrops drop correctly? Let's know the correct way to drop eyedrops.
Is it true that eyedrops directly drop onto the eyeball and destroy the eyes
When it comes to the use of eyedrops, many people are used to dropping eyedrops on the eyeball, but in fact, this method is wrong! Not only that, eyedrops directly drop on the eyeball to destroy the eyes, because after the solution stimulates the cornea, the number of blinks increases, making the solution outflow and reducing the efficacy. At the same time, drug contact with cornea directly will also bring more drug-induced damage to cornea. Many little friends said after reading it, the first half of their lives of eyedrops are all white. Every time, no matter what happened, just drop them into their eyes. It's subversive.
How to drop eyedrops correctly
1. Clean your hands. There are too many things that your hands touch. If bacteria infect your eyes, it is recommended to clean your hands before dropping eyedrops.
2. Open the eyedrop bottle, pay attention to this step, and do not put the cap down, because it is easy to contact bacteria when the cap is down, and bacteria entering the eyedrop bottle will increase the risk of infection. The correct way is to lie down or put it up according to the shape of the cap.
3. Gently pull down the lower eyelid. After pulling it open, the conjunctival sac between the lower eyelid and the eyeball will be exposed.
4. Drop the medicine into the conjunctival sac. Please note that the position of the drops here is conjunctival sac, not black eyeball. This step is very important. If you drop it wrong, it will hurt your eyes!
5. Pay attention to close eyes and press the angle of inner eye with fingers for 2 minutes after dripping. Close your eyes for about 3 minutes after ordering eyedrops, but do not close your eyes too hard to prevent the liquid from squeezing out. At the same time, press the inner corner of the eye with your finger to prevent the liquid from flowing into the nasal cavity along the nasolacrimal duct.
Many people are used to dropping eyedrops directly on the black eyeball. In fact, this is the wrong way to drop eyedrops directly on the black eyeball, which will stimulate the cornea and lead to the outflow of too much eyeblink solution. In addition, it should be noted that the eye drops should be suspended in the air, and the mouth of the bottle should not touch the eyelashes to prevent pollution. Because the conjunctival sac volume is limited, one drop is enough.
Contraindications of eye drops
1. Eye drops also have a strict shelf life. When you don't use them at ordinary times, you must keep them. The unopened liquid medicine ointment shall be stored in the refrigerator or placed in a cool place away from light. Do not blindly use ophthalmic drugs that have expired or whose color has changed significantly. The ingredients in ophthalmic drugs often have changed, which can cause inflammatory stimulation or allergic reaction.
2. Eye drops are products that directly contact the eyes, so it is necessary to pay attention to the use method. Since the eye drops and ointment are directly exposed to the air after opening the bottle, it is inevitable to contact with the eyes when dropping, resulting in pollution. Therefore, the first drop of eye drops and ointment should be removed before dropping into the eyes.
3. Not all people are suitable for eyedrops. When acute inflammation is accompanied by a large amount of eye secretions, eye ointment should be used after removing the secretions.
4. When the local congestion of ocular inflammation is obvious, hot compress can be applied first, and then eye drops can be used, with better effect.
5. The method of eye drops is very important. If you drop it wrong, it will hurt your eyes! When you drop the eye drops, you can gently pull down the eyelids. After exposing the conjunctiva of the fornix, you can apply the water or ointment to the conjunctival sac. Each time you drop 1-2 drops of the water, the ointment will be full of the conjunctival sac. When dripping, the mouth of the bottle should be properly away from the affected eye to avoid pollution caused by touching the eyelashes, so that the uninfected eye may be infected due to the use of the same bottle of ophthalmic medicine.
6. If the inner package of eye drops is composed of normal saline and drug powder (such as rifampicin), it should be mixed by itself and then used, otherwise, it is just a drop of normal saline.
