Is Your Vision Blurry? A Complete Guide to Cataract Causes and Treatments [Dr. Oh Young-sam, IOK Column]

Have you ever woken up in the morning or stepped into bright light only to find your vision unusually blurry? If you think it's just fatigue, think again—it could be a sign of cataracts. Cataracts are the leading cause of blindness worldwide, with a significantly higher incidence in people over 60. So, why do cataracts occur, and how can they be treated?

What Are Cataracts? Causes and Symptoms

A cataract is a condition where the eye's natural lens becomes cloudy. Normally, the lens is clear like a camera lens, but when cataracts develop, it turns opaque, leading to blurry vision and increased sensitivity to light.

The most common cause is aging. According to the Korean Ophthalmological Society, 70% of people in their 60s experience early-stage cataracts, and by their 80s, over 90% are affected. Other causes include diabetes, smoking, UV exposure, and prolonged steroid use.

Stages of Cataracts and Treatment Options

Cataracts progress through three stages:

Early Stage: Slight blurriness and light sensitivity, but no major impact on daily life. Regular eye check-ups are recommended.
Intermediate Stage: Noticeable vision impairment, such as blurred or double vision. Surgery should be considered.
Advanced Stage: Severe visual impairment making daily life difficult. Surgery is the only solution.

Do You Really Need Cataract Surgery?

Some hesitate to undergo surgery, but modern cataract surgery is safe and effective. Dr. Oh Young-sam from Gangnam IOK Eye Clinic explains, "Cataract surgery removes the cloudy lens using ultrasound and replaces it with an artificial lens. The procedure takes just 10–15 minutes, and patients can return to daily activities the next day."

Additionally, premium multifocal lenses allow both cataract removal and presbyopia correction, improving overall vision quality.

How to Prevent Cataracts

While cataracts cannot be completely prevented, their progression can be slowed:

UV Protection: Wear UV-blocking sunglasses to protect your eyes from harmful rays.
Healthy Diet: Eat foods rich in lutein, zeaxanthin, and vitamin C (spinach, broccoli, etc.) for better eye health.
Regular Eye Exams: People over 40 should have annual check-ups, while those over 60 should visit an eye specialist every six months.
