Dangerous habit: why you shouldn't blow into the eye when dust gets in it

Blowing into the eye when dust, an eyelash, or another small object gets in it is a common but unsafe first aid method. Here's why you shouldn't do this:

Bacteria and microbes from the mouth

The human mouth contains a huge number of bacteria. When you blow, especially from a close distance, particles of saliva along with microbes can get into the eye. This can lead to inflammation, irritation, or even conjunctivitis.

Increased irritation

A strong air flow may not remove the foreign body, but instead push it deeper under the eyelid or scratch the cornea. This increases the risk of eye damage and worsens the situation.

Ineffectiveness

Blowing into the eye is almost always useless. Dust particles or eyelashes often cling to the mucous membrane or remain under the eyelid, and air cannot simply "blow them out".

What to do correctly:

Don't rub your eye. This can increase damage.

Blink frequently. Tears can remove small particles on their own.

Rinse the eye with clean water or saline solution.

If nothing helps and discomfort persists - see a doctor.

Blowing into the eye is a habit that seems harmless but can do more harm than good. It's better to use safe and proven methods.
