Many people use eye drops when they are dry and tired, but many people have misunderstandings in their use, and these misunderstandings often damage the eyes.
1. Uncomfortable eyes, drop eye drops?
Yang Shasha, an attending physician of the Department of Ophthalmology, Guangzhou First People's Hospital, said that there are many reasons for eye fatigue, and it is necessary to find the cause and the right medicine. If the secretion of tears is insufficient, use eye drops that simply supplement the tears; if there is inflammation, use eye drops with anti-inflammatory function; if you need long-term use because of dry eye, you can not use eye drops containing preservatives, otherwise it will hurt your eyes. .
2. How to drop eye drops?
Eye drops should not drip on the black eyeballs, but rather open the lower eyelids and drop the eye drops onto the conjunctival sac below the eyes. Yang Shasha explained that this is because the black eyeball is a cornea and it feels very sharp. When the eye drops drip onto the cornea, people will feel uncomfortable immediately.
The correct posture should be: head tilted back, eyes looking at the top of the head, eye drops bottle hanging in the eyes 2 cm ~ 3 cm, the index finger pulled down the eyelids to expose the conjunctival sac, the eye drops into the conjunctiva.
3. Did the eye drops open or close your eyes?
Yang Shasha reminded that after dropping the eye drops, the eyes should be gently closed, and the inner corner of the eyes should be gently pressed with the fingers. Pressing for two or three minutes can reduce the discharge of eye drops through the lacrimal passages and increase the curative effect.
4. Are there any order of eye drops and eye ointments?
Yang Shasha introduced that when using several eye drops at the same time, it is fine to drop any one. However, it should be noted that the use of two eye drops must be between 5 minutes and 10 minutes. Otherwise, the previous eye drops have not been absorbed, and the latter drops will dilute and wash away the front, which is equivalent to white drops.
For the same reason, if it is eye drops and eye ointment, you should first drop the eye drops and then use eye ointment after 10 minutes.
5. How many drops are you going to get fast?
Yang Shasha said that if the method of use is correct, a drop of eye drops will suffice. Because the volume of one drop of eye drops is larger than the volume of the conjunctival sac of the eye, if there is more drops, it will only be wasted.
6. Can you continue to use it without a shelf life?
Eye drops are usually labeled for two or three years, but generally refer to unopened conditions. Eye drops are easily infected by microorganisms in the air after opening, resulting in failure or substances that are harmful to the eyes.
Therefore, the eye drops should be used up within one month after opening. If you want to extend the shelf life after opening, you can put it in a refrigerator at 4 °C, but it can only be extended to two or three months. So don't use expired eye drops for fear of wasting.
