Winter is an even more difficult season for 2 million dry eye patients. This is because the cold and dry weather worsen the discomfort in the eyes. The causes of dry eye are very diverse, but the most common treatment is to moisturize the dry eyes with artificial tears and to supplement the decreased tear function. However, it is not good to use too much artificial tears at once. Let's learn the proper way to use artificial tears.

◇Putting in a large amount at once reduces stability... Only one drop at a time

Let's understand the principle of dry eye syndrome. Dry eye syndrome is a condition where, due to various causes, tear secretion decreases or tears are secreted in large amounts but undergo changes in their composition, leading to symptoms such as dry eyes. Dr. Choi Jin-young of Irium Eye Clinic said, "Tears are composed of three layers: the oil layer, the aqueous layer, and the mucin layer at the very bottom." He explained, "When the aqueous layer is deficient or the oil layer is unstable, dry eye syndrome occurs." Artificial tears are used to supplement the aqueous layer. However, it is not recommended to put more than necessary into the eyes without consulting a doctor.

Director Choi said, "Administering a large amount of artificial tears at once for moisture may be beneficial for the aqueous layer, but it can actually decrease stability in the mucin layer." He added, "This can destabilize the tear film, leading to dryness, and increasing the amount does not necessarily produce a greater effect." Excessive eye drops without medical consultation or follow-up observation are not very helpful.

Like other eye drops, artificial tears should be used with only one drop per application. Even one drop can be sufficiently effective. However, it is important to always carry them and apply 'frequently' whenever dryness is felt. Preemptively applying one drop before situations that may cause symptoms can also be effective. For example, if tears flow when exposed to wind, use it before going outside; if you experience dryness or fatigue after reading for a long time, use it before reading. When using artificial tears, the first 1-2 drops should be discarded because fine plastic particles may be mixed during the opening process. It is also advisable to choose a type that feels comfortable for your eyes. Properly use the product prescribed by an ophthalmologist after a check-up to ensure correct application.

◇If you have Mybomsaem issues, apply warm compresses and clean your eyelids.

Many cases of dry eye syndrome are caused by problems with the meibomian glands. The meibomian glands are oil glands located inside the eyelids, and they secrete lipids to prevent excessive evaporation of tears. However, when these glands are continuously exposed to bacteria or waste products, the lipids harden, and if the meibomian gland ducts become blocked, the tear film becomes unstable, leading to dry eyes. Director Choi Jin-young stated, "People with meibomian gland dysfunction may feel temporary relief using artificial tears, but it doesn't address the root cause," and added, "In such cases, cleaning the eyelids can be helpful." To see proper results, the method is important.

Director Choi said, "First, you should warm your eyes with a warm compress to melt the oil, and while keeping your eyes closed, gently lift the upper eyelid and carefully wipe the area where the eyelashes emerge." According to a study by Harvard Medical School, applying a 15-minute warm compress to patients with dry eye syndrome increased the lipid components of the tear film, improving dryness. Especially for those who frequently experience eyelid inflammation, eyelid parasites could be the cause. Director Choi stated, "People like this should be cleaned with a cleanser containing tea tree oil to recover."
