Everyone, let me ask you a question.
How well are you taking care of your eye health?
Using smartphones on your commute,
staring at monitors at work every day,
and watching Netflix or YouTube at home,
your eyes are constantly moving all day. If not properly managed,
they can quickly become fatigued,
and even lead to serious problems.
Among these, dry eye syndrome is one of the most common conditions affecting modern people.
If you are concerned about dry eyes
and frequently use artificial tears and eye drops,
I highly recommend reading this article to the end.
We will explain in three parts which ingredients in eye drops can help protect your eye health.

What is dry eye syndrome?
This condition is a common ailment caused by smartphone habits,
surpassing conditions like 'turtle neck syndrome' and insomnia to rank first, with many people
complaining of eye fatigue and pain.

This condition occurs when there is an excessive lack of tears, which act as a lubricant for the eyes, leading to symptoms such as dry, gritty eyes,
a foreign body sensation, or easily fatigued eyes.
In particular, a survey showed that over 90% of Koreans
have experienced symptoms of dry eyes in this way.
Typically, busy office workers often choose to get dry eye drops prescribed
or frequently use artificial tears to solve the problem, rather than visiting a hospital.

However, did you know that using eye drops without knowing your eye condition
can cause even greater eye fatigue?
You need to choose ingredients that suit you, depending on the formulation of the eye drops, the presence of preservatives, and the frequency of instillation.
I will explain this in detail below.
Recommended Ingredients for Dry Eye Drops
For this part, it is helpful to have a basic understanding of the structure of the eye surface.
Aqueous Layer
Mucus Layer
Lipid Layer
This is because each layer can have different problems,
and thus requires different active ingredients in eye drops.

<1> Aqueous Layer Abnormality
(Hyaluronic acid, Povidone, CMC, HEC, HPMC, PVA)
Generally, these ingredients are used to supplement insufficient tears (moisture) in the eyes,
serving to replenish the aqueous layer.
If there is a problem in this area, using artificial tears alone
can alleviate the symptoms.
<2> Mucous Layer Abnormality
(Diquafosol)
Diquafosol has been shown to improve symptoms related to dry eye syndrome
(corneal and conjunctival epithelial disorder = symptoms of damage to the eye surface),
and has even been published as a paper in the Journal of University Ophthalmology.

<3> Lipid Layer Abnormality
(Glycerin, Glycol, Carbomer)
This usually occurs when there is an abnormality in the meibomian glands,
and ingredients that supplement the lipid layer should be used to address the problem of improper oil secretion.
These three layers are essential components for tear production,
so none should be deficient. If you need an accurate diagnosis for these issues,
please consult through the link below.

Are dry eye drops alone enough?
In fact, this condition is not easy to resolve if the living environment does not change,
and if not managed, damage to the eyes accumulates, and the problem worsens.
In our clinic alone, the number of dry eye patients is increasing, and statistics from the Health Insurance Review & Assessment Service also show
that medical expenses are steadily rising.

Notably, this problem rarely appears in teenagers but
occurs across various age groups from their 20s to 70s.
Therefore, from a medium to long-term perspective, it is important to get a diagnosis and treatment from a specialized ophthalmologist,
as simply relying on eye drops, artificial tears, or eye washes alone
may lead to problems in the future.

Symptom Relief Methods
If it's a simple and mild problem, it's best to frequently instill artificial tears or
eye drops with ingredients suited to your needs, and blink your eyes often.
However, if there is a problem with the lipid layer, accompanying blepharitis treatment
should be received at a specialized ophthalmology clinic,
and regular warm compresses should be applied.
Information on warm compress methods is available on our official YouTube channel,
so please refer to it.
<Conclusion>
Even after reading this post to the end,
I believe there are certainly people who cannot visit a hospital due to lack of time or being too busy.
However, you really need to think carefully.
Your eyes are not like arms or legs that can be reattached after being damaged, or become stronger after complete recovery.
They are also not like teeth that can be replaced if broken or problematic.
Even as you read this, fatigue and damage are accumulating in your eyes.
If you neglect your eye health and fail to manage it,
a bigger problem may arise later.
Please visit a nearby ophthalmologist or hospital to get your eyes diagnosed properly,
and receive appropriate treatment to protect your precious eyes.
