Eye drops should not be used casually

Director Ye Jianzhang of the Department of Cornea and Ophthalmology of Dongguan Aier Eye Hospital popularized science for us: eye drops are local drug preparations containing drugs, which are absorbed through our ocular surface tissue and penetrate into the eye through the cornea. Different eye drops are used by different eye diseases, and the effects of different eye drops are also different, and sometimes they may need to be used in combination to achieve the desired treatment effect.

Antibacterial, antiviral, anti-allergic, anti-glaucoma, anti-inflammatory drugs, artificial tears, and anti-fatigue drugs are the seven types of eye drops commonly used on the market, and there are many types that are not commonly used. We often say, "prescribe the right medicine", so remember not to buy and use so many types of eye drops at will.

Misconceptions about eye drops

Myth 1

Eye drops are used for a long time after opening

Most eye drops are added with preservatives to inhibit bacterial growth, and this can last up to a month after opening; Some eye drops do not have preservatives added and are generally packaged in small packages, which should be used up within 24 hours; Some eye drops also need to be stored in the refrigerator, please refer to the instructions for details.

After the expiration of eye drops, not only will the effectiveness be reduced, but it will also be easily contaminated by bacteria, so it is best not to use them. Some people will judge whether the product can be used by color, flocculents, etc., but some eye drops are suspensions, so it is recommended to refer to the instructions.

Myth 2

Dripping on the black eyeballs

The front layer of the black eyeball is our cornea, which has many nerve endings on it, which is very sensitive, and when stimulated by eye drops, it will produce reactions such as blinking and tear secretion, causing the medicine to overflow and lose its effectiveness.

After washing your hands, tilt your head back. Gently open the lower eyelid with your fingers, look up, drop the medicine into the conjunctival sac of the lower eyelid, and gently close your eyes and rest for 2 minutes.

Note! Do not touch the eyelashes at the mouth of the bottle.

Myth 3

Lots of potions

The conjunctival sac has a limited capacity, and the amount of one drop is just right. In order to pursue efficacy, the drug may be absorbed throughout the body through the eye mucosa, resulting in side effects.

As long as it is done correctly, no potion spills, one drop at a time is enough. If you need to use multiple potions at the same time, use them at intervals of more than 5 minutes to avoid affecting the effect.

Myth 4

Wearing contact lenses eye drops

Some eye drops cannot be used with contact lenses, otherwise the ingredients in them will stick to the glasses and cause adverse effects. It is recommended to check the instructions before use.

Myth 5

Don't pay attention to the expiration date

Eye drops usually containing preservatives are effective within 4 weeks after opening; Preservative-free eye drops have a shorter shelf life, some even for just one day.

Do not use it again after the expiration date, regardless of whether it has been used up or not. After opening, the medicine bottle should be stored in a cool and dark place, and it is best not to carry it close to you to prevent the medicine from heating up and deteriorating.

Myth 6

Blindly follow the trend and abuse

There are a dazzling array of Internet celebrity eye drops on the market, and many people follow the trend to buy and use them, and they are completely unsure whether they are suitable for them. If you have symptoms such as dry eyes, astringent eyes, and itchy eyes, do not self-medicate, and have an ophthalmologist find out the cause and prescribe the right medicine.

Myth 7

After dropping one eye drop, drop the next one immediately

There are also compatibility and contraindications between eye drops, just like cold medicine, so if you need to drop a variety of eye drops, be sure to do it under the guidance of a doctor.

After using one, drop one at intervals of 5~10 minutes to give the eyes enough time to absorb.

Myth 8

Share a bottle of eye drops

Eye drops are personal items and cannot be shared with others.

On the one hand, everyone's situation is different, if mixed may not be symptomatic, it may also cause allergies; On the other hand, if the previous person uses it improperly and contaminates the mouth of the bottle, the next person may become infected when they use it, so do not use eye drops with each other.
