Ask if you don’t understand
The eye drops have been opened for a long time,Can it still be used?
Better not use it
Because modern people face electronic products every day, dry eyes and sore eyes have become commonplace. At this time, the eye drops have become a good helper, and a few drops of it can alleviate the discomfort immediately.
The following three common misunderstandings may affect the effect of eye drops and even cause damage to the eyes.
Misunderstanding one
The eye drops have been in use for a long time after opening
Most people use eye drops when they feel uncomfortable in their eyes, and just put them away when they don’t need them. You can’t remember how long it’s been before you use them next time.
In fact, once the eye drops are opened, they may be contaminated by microorganisms and deteriorate easily.
The ophthalmic preparations can be used for up to 4 weeks after activation, and some products will be shorter or longer. The “Precautions” in the eye drops instructions will be clearly stated. This time refers to the maximum time that can be used after opening.
Using expired eye drops, the active ingredients in it may not only become invalid, but it may also bring more risks due to microbial growth.
If you have eye drops that have been opened for more than one month at home, it is recommended not to use them. Next time you buy eye drops, you can write the opening date on the bottle.
Misunderstanding two
Many drops of eye drops at a time
Many people use a lot of eye drops at a time. In fact, there is not so much medicine in the conjunctival sac of the eye.
Generally, one or two drops at a time is enough, and the important thing is to place the drops in the right place.
Misunderstanding three
Drop the eye drops on the eyeball directly
When using eye drops, it is not recommended to drop them directly in the middle of the eyeball. Doing so will irritate the eyes to blink and shed tears all the time, making the eye drops drain out more quickly without any effect.
The correct method is to gently pull down the lower eyelid to form a small sac, and drop the eye drops into the small sac.
Finally, I would like to remind you that many popular Japanese eye drops on the market have some prescription drugs added. You must be cautious when buying or using them. It is best to consult a professional doctor or pharmacist.
If your eyes are tired or dry, artificial tears such as sodium carboxymethyl cellulose eye drops and polyvinyl alcohol eye drops are sufficient.
