First aid for eye entry into a foreign body.

As the saying goes, "the eyes are the windows of the soul", and the eyes are the sensory organs of the human body that directly perceive the colorful external world. In daily life, accidents often occur when foreign bodies get into the eyes.

After the foreign body enters the eye, it can immediately cause different degrees of intraocular foreign body sensation, pain and reflex tearing, which can cause eye damage and visual function in severe cases, and reduce vision in mild cases, and completely lose vision in severe cases. Therefore, it is important to prevent the occurrence of eye trauma and properly manage foreign bodies into the eye.

So what to do when a foreign body gets into your eye?

Method 1: Do not rub your eyes with your hands after a foreign body enters your eyes to avoid the foreign body abrasion the cornea. The correct way to deal with it is to calmly close your eyes and rest for a while (if you are a child, you should control your hands first, so as not to rub your eyes) and wait until the tears are secreted in large quantities and continue to burst out of the eyes, and then slowly open your eyes and blink a few times, in most cases, a large amount of tears will automatically "flush out" the foreign body in the eye.

Method 2: If tears cannot flush out the foreign body, prepare a basin of clean water, gently close your eyes, immerse your face in the basin, and blink your eyes in the water a few times, which will flush out the foreign body in the eyes. You can also ask someone to open the affected eye, fill the eye with cold boiled water or saline with a syringe, or rinse the eye with a cup.

Method 3: If the foreign body cannot be flushed out by various irrigation methods, you can ask someone or yourself to open the eyelids and gently wipe off the foreign body with a cotton swab or a clean handkerchief dipped in cold boiled water or normal saline.

Method 4: If none of the above methods are effective, it may be that the foreign body has trapped in the eye tissue, and you should immediately go to the hospital and ask an ophthalmologist to remove it. Do not pick with a needle or wipe or pick with other unclean objects, so as not to damage the eyeball and cause purulent infection of the eyeball.

After the foreign body is removed, some eye drops or ointment can be appropriately instilled to prevent infection.

Tetracycline eye ointment is then injected into the eye and the eye is blinked repeatedly to squeeze the paint and ointment out of the eye.

Dust When dust enters the eyes, you can ask someone to help you open the eyelids and gently lick the surface of the eyeball a few times with the tip of your tongue to lick the dust out of the eyes; If there is no one else, you can try to make yourself cry and wash the dust out of your eyes.
