How Fine Dust Affects Eye Health
Could my dry eyes be due to fine dust?
Many people say that their dry eyes feel worse on days with severe fine dust.
Is it true? A question I've been curious about!!

Last week, I saw a lot of news about 'Beijing's Worst Sandstorm'.
Every article described it as a real scene, not from a disaster movie,
and while discussing the severity of sandstorms and yellow dust,
they also mentioned that the yellow dust warning was only at the second level out of four,
suggesting it was closer to smog than just sand.
Watching that news, I felt that this spring, too, we would suffer from yellow dust and fine dust.

✨ Fine dust, ultrafine dust, yellow dust!! How much do you know about the difference?
Fine dust, ultrafine dust, yellow dust, which are always present in today's weather!!
Do you know the difference?
Yellow dust is a phenomenon where soil dust or sand is carried by strong winds from the desert regions of northern China or Mongolia and falls onto the ground.
Fine dust and ultrafine dust are very small particles.
Fine dust has a diameter of 10㎛, and ultrafine dust is 2.5㎛,
which is said to be smaller than a strand of hair.


✨ Is fine dust related to eye health?
On days with 'bad' fine dust, many people complain of eye discomfort or stinging.
Safety alerts also mention the risk of abnormal symptoms like coughing, shortness of breath,
itching, and dry eyes on days with bad fine dust,
so it can be seen that it affects eye health.

✨ Eyes! Why are they particularly vulnerable to fine dust?
Our eyes are one of the body parts where the mucous membrane is exposed externally,
making them sensitive to external stimuli.
When harmful fine dust settles on the mucous membrane or corneal surface,
it can increase the risk of tear film destruction, allergic conjunctivitis,
and dry eyes, so caution is needed.


👍Life hacks for eye health on days with severe fine dust!
1. Minimize outdoor activities if possible.
2. Pay attention to cleanliness after going out! Apply a warm compress for 5-10 minutes.
3. Consciously focus on blinking your eyes.
4. Drink plenty of water regularly!
5. Use artificial tears an appropriate number of times to keep your eyes from drying out.
6. If you usually suffer from severe dry eyes, visit an eye care specialist.

In fact, many people visit our clinic for ongoing management due to concerns about meibomian gland dysfunction and dry eyes.
While mild dry eyes are common nowadays,
if the condition worsens, some people experience discomfort such as vision impairment,
so please remember that it's best to manage it proactively.
