Neglected Dry Eye Syndrome Can Lead to Blindness [Dr.OhYoung−sam’sIOKColumn]

 In recent years, the widespread use of smartphones and computers has left many modern individuals with little time to blink. As we spend longer hours exposed to stimulating videos and intense light, our eyes inevitably become drier. However, many people dismiss symptoms such as gritty or stinging eyes as merely “simple fatigue.” Is it truly safe to leave these signs unchecked? Dry eye syndrome, caused by insufficient tear production or excessive tear evaporation, often begins with mild dryness but can gradually worsen without proper management—leading to impaired vision, corneal damage, and in severe cases, even blindness.

According to a report by the World Health Organization (WHO), over 30% of the global population experiences symptoms of dry eye syndrome. Furthermore, data released by the Korea Health Management Association indicates a more than 20% increase in dry eye patients in Korea over the past five years. Such high prevalence and rapid growth show that many people overlook the early warning signs from their eyes.

How, then, can we prevent and manage dry eye syndrome? The most fundamental approach is to ensure your eyes get sufficient rest. If you use digital devices for extended periods, you should look into the distance at least once every 20 minutes to give your eyes a break. Additionally, using artificial tears to replenish moisture or maintaining indoor humidity at around 40–60% can significantly help alleviate dryness.

Yet, attempting to manage dry eye on your own may not always pinpoint the precise cause, and treating already damaged eyes can be difficult. According to Dr. Oh Young-sam at Gangnam IOK Eye Clinic, “Dry eye syndrome is more than just a feeling of ‘grittiness.’ It can lead to various complications, including keratitis or conjunctivitis, which is why professional diagnosis and treatment are crucial.” He continues, “Consider the case of an office worker, Mr. A, who spent extended hours in front of a monitor. Severe dryness eventually led to deteriorating vision. Fortunately, he sought treatment early enough at our clinic to receive specialized care and recovered without major after-effects. However, if he had waited longer, complications could have progressed, making treatment more challenging.”

At Gangnam IOK Eye Clinic, customized treatment plans are formulated by taking into account the patient’s occupation, lifestyle habits, and unique eye structure. In the early stages, management programs that stabilize the tear film, along with artificial tears or medication, are utilized. In more severe cases, laser procedures or corneal protection methods are employed to alleviate symptoms. Moreover, comprehensive guidance on improving indoor environments and adjusting daily habits is provided to minimize recurrence.

Eyes are extremely delicate organs that require a long time to heal once they are damaged. If dry eye syndrome progresses and worsens, impaired vision and multiple complications may quickly follow. In fact, a lack of moisture in the eyes accelerates corneal damage, which can lead to blindness in the worst scenarios.

Are your eyes healthy right now? If you feel even slight discomfort, why not consider getting a professional examination instead of leaving the symptoms ignored?
