A few years ago, my father started noticing that his vision was getting cloudy. At first, he brushed it off as just “getting older,” but over time, things got worse. Night driving became nearly impossible, bright lights created painful glare, and even reading a book felt like staring through a fogged-up window.
After months of frustration, we finally saw an eye specialist who confirmed what we had suspected—cataracts.
What Causes Cataracts?
The doctor explained that cataracts develop when the proteins in the eye’s natural lens start to break down and clump together, causing cloudiness. The most common cause? Aging. However, other factors like UV exposure, smoking, diabetes, and even prolonged use of steroids can speed up the process.
At first, the symptoms were mild, and he managed with stronger glasses and brighter lighting. But as time went on, his vision declined to the point where daily activities became difficult. That’s when we knew it was time for cataract surgery.
When is Cataract Surgery Necessary?
The general rule is: if cataracts start affecting your quality of life, it’s time to consider surgery. For my dad, that meant struggling with:
Blurry vision that glasses couldn’t fix
Difficulty seeing in dim or bright light
Increased sensitivity to glare
Trouble recognizing faces or reading signs

This surgery completely changed my father’s life, and I hope this helps someone else make the right decision!
A couple of years ago, I started noticing something strange. Driving at night became difficult—streetlights looked like they had halos around them. Reading small text felt harder, even with my glasses, and everything started to look… dim.
At first, I thought it was just eye strain from too much screen time. But when I caught myself squinting in broad daylight just to see clearly, I knew something was wrong. A visit to the eye doctor confirmed it: I had cataracts.
What Causes Cataracts?
The doctor explained that cataracts are basically a clouding of the eye’s natural lens. Most people get them as they age, but other factors can speed up the process, including:
Too much UV exposure – Years of not wearing sunglasses can take a toll. Eye injuries or previous surgeries – Trauma can cause early cataract formation. Medical conditions like diabetes – High blood sugar can affect the eyes. Certain medications (like steroids) – Long-term use can increase risk. Genetics – Some people are just more prone to developing them early.
In my case, it was a mix of aging and too much sun exposure over the years. The doctor said I’d eventually need surgery, but I wasn’t ready—so I waited.
When Is Cataract Surgery Necessary?
At first, my vision was still manageable, so I put off surgery. But over time, things got worse:
Driving at night became dangerous – Headlights from oncoming cars were blinding. Colors looked faded – Blues and purples looked like dull grays. Even strong glasses didn’t help – No prescription could fix the blurriness.
That’s when I knew—it was time for cataract surgery.

I researched top eye clinics in Seoul and came across SNU Eye Clinic and Dr. Chung Eui Sang. What convinced me to go there?

Expert Surgeon – Dr. Chung is one of the best ophthalmologists in Seoul, with extensive experience in cataract and refractive surgery.

My Cataract Surgery Experience
Honestly, I was nervous before the procedure, but Dr. Chung and his team made everything so easy. The surgery itself was painless—I was awake but completely comfortable. Afterward, my vision was a little blurry for a few hours, but by the next day…
I could see colors vividly again! Everything was crisp and clear! No more halos around lights!
It felt like someone had wiped away a foggy window—I hadn’t realized how much I was missing.

Cataracts occur when the eye’s natural lens becomes cloudy, leading to blurred or hazy vision. This cloudiness results from the breakdown and clumping of proteins within the lens. Several factors can contribute to the development of cataracts, including:
- Aging: The most common cause, as proteins in the lens degrade over time.
- Diabetes: Elevated blood sugar levels can lead to lens swelling and protein denaturation.
- Excessive Sun Exposure: Ultraviolet (UV) radiation can damage lens proteins.
- Smoking: Introduces toxins that can accelerate lens deterioration.
- Obesity: Associated with metabolic changes affecting lens health.
- Eye Injuries or Inflammation: Can lead to traumatic cataracts.
- Prolonged Use of Corticosteroids: These medications can increase cataract risk.
When cataracts progress to the point where they interfere with daily activities—such as reading, driving, or recognizing faces—surgical intervention becomes necessary. Cataract surgery involves removing the clouded lens and replacing it with a clear artificial intraocular lens (IOL). This procedure is highly effective, with a success rate of approximately 98%.

A few months ago, my aunt started complaining about blurry vision, even though her glasses prescription hadn’t changed. She noticed that colors seemed dull, and driving at night became difficult because of glare and halos around lights. At first, she assumed it was just eye strain, but over time, her vision kept getting worse.
Worried, we took her to SNU Eye Clinic in Seoul, where she met Dr. Chung Eui Sang, an expert in cataract diagnosis and surgery.
What Causes Cataracts?
Dr. Chung explained that cataracts develop when the eye’s natural lens becomes cloudy, blocking light from passing through clearly. The most common causes include:
Aging – The most common cause, as proteins in the eye lens break down over time.
Sun Exposure – UV rays can accelerate lens damage.
Diabetes – High blood sugar can cause earlier cataract formation.
Smoking & Alcohol – Lifestyle factors that increase oxidative stress on the eyes.
Eye Injuries or Surgery – Trauma or previous eye procedures can trigger cataracts.
Long-Term Steroid Use – Certain medications can contribute to early cataract formation.
When is Cataract Surgery Necessary?
Dr. Chung said that early-stage cataracts don’t always require surgery. Many people manage with stronger glasses, brighter lighting, or anti-glare coatings on their lenses. However, surgery is necessary when:
Blurry vision starts interfering with daily activities like reading, driving, or watching TV.
Colors appear faded or yellowish, making it hard to differentiate shades.
Increased sensitivity to light and glare, especially when driving at night.
Frequent prescription changes, but no improvement in vision.
My aunt was at a point where her cataracts were significantly affecting her life, so Dr. Chung recommended cataract surgery.
