Protect your eyes and use eye drops correctly

  Eye drops are one of the commonly used drugs for eye diseases. For many eye diseases, eye drops have a direct and rapid therapeutic effect. With the changes in people’s lifestyles and working conditions, people spend more and more time with their eyes, such as watching computers, online classes, and playing video games for a long time, and they are prone to visual fatigue and dry eyes. Both of these symptoms are characterized by dry eyes and discomfort, so many people turn eye drops into a daily “essential medicine”. Once the eyes are uncomfortable, they will randomly apply a few drops. In fact, eye drops, in principle, can be used without any need for routine use.
Commonly used eye drops, avoid 3 types of ingredients

  The main ingredients ending with “pine” are dexamethasone, betamethasone, prednisone, cortisone, etc. Such eye drops belong to steroid drugs, which contain hormones. This type of eye drops should be used reasonably under the guidance of professional physicians and has a good effect on eye inflammation, but long-term or large-scale use without authorization may cause increased intraocular pressure.
  The main ingredients ending with “floxacin” and “su” are ofloxacin, levofloxacin, tetracycline, chloramphenicol, neomycin, etc. These are antibiotic eye drops. Improper use may cause imbalance of the eye flora and cause serious infections.
  The main ingredients ending with “oxazoline” are naphazoline hydrochloride, oxymetazoline hydrochloride, tetrahydrozoline hydrochloride and so on. These components are adrenergic receptor agonists, which can shrink conjunctival capillaries and remove red blood. If such eye drops are used for a long time, the effect will become worse and worse. After a sudden stop, the blood vessels will rebound and expand, even more serious than before. Moreover, the side effects of such eye drops are very serious, which may cause increased blood pressure and aggravate the risks of cardiovascular or endocrine diseases.
  If you want to use eye drops to relieve eye fatigue, artificial tears without preservatives are a safe choice. The main ingredients are sodium hyaluronate, carboxymethyl cellulose, carbomer and so on. You can try different brands and choose the one you feel most comfortable with.
  It should be reminded that artificial tears that do not contain preservatives cannot be abused and used for a long time. If you feel unwell after dripping, you should go to the hospital for examination in time.
4 steps for correct use of eye drops

  Different types of eye drops have different effects. When using, you need to strictly follow the following steps and pay attention to the main points to master the correct method of eye drops to ensure that the eye drops can maximize the effect.
  1. Before use, check the name of the medicine, check the dose to be dripped, make sure that the medicine is within the shelf life, and then check for discoloration, odor, turbidity, etc. If the preparation itself is of muddy oil type, shake it gently before use to ensure the consistency of the drug solution.
  2. After preparing the potion, wash your hands clean as soon as possible to avoid bacterial infection during use.
  3. Gently tilt your head back and look toward the top of your head. The index finger pulls down the lower eyelid to expose the conjunctival sac. Drop the eye drops into the conjunctival sac at a place 1 to 2 cm above the eye.
  4. Use the middle finger to gently press the nasolacrimal duct between the inside of the nose and the corner of the eyes to prevent it from being absorbed into the mouth. Open the mouth when dripping, so as to maintain the posture. Then close your eyes for 5 minutes.
3 major misunderstandings in the use of eye drops

  Misunderstanding 1: You can continue to use it before the expiry date. In fact, the shelf life on the packaging of eye drops usually refers to the unopened bottle, which is generally 1 to 3 years. Most eye drops contain preservatives. Once opened and used, the liquid medicine may be contaminated by microorganisms in the air, causing safety hazards.
  Misunderstanding 2: Long-term frequent use. Any type of eye drops should be used at the prescribed frequency and treatment time. Excessive use may cause adverse reactions. Long-term use of hormonal eye drops may lead to diseases such as glaucoma and cataracts, and may also cause serious eye infections, including fungal infections of the cornea.
  Misunderstanding 3: Use multiple eye drops together. When multiple eye drops are needed, it is recommended not to drip them into the eyes at the same time. There is a sequence of eye drops. The first is to be absorbed quickly, and the ointment is slow to absorb. Therefore, you should instill the eye drops during the day and then apply the ointment at night. Secondly, when both eye drops are both eye drops, the less irritating one should be applied first, and the more irritating one should be applied later. Finally, 15 minutes after the first eye drop has been dripped, drip the other one, and the interval should not be too short, so as not to affect the efficacy.
