Early Cataract Self-Diagnosis: 6 Key Warning Signs


Welcome. This is BGN Eye Clinic located at Jamsil Lotte Tower.

At our clinic, ophthalmologists from various specialties collaborate to evaluate your ocular health from multiple clinical perspectives. We are dedicated to providing reliable, accurate information regarding vision correction and eye health.

Early Cataract Sign 1: Has Your Field of Vision Begun to Blur?

Recently, many individuals express concern over difficulty reading fine print or experiencing halo effects and light scattering around lamps. Differentiating the underlying causes of vision changes on your own can be highly challenging. Here is an overview of key warning signs based on everyday visual disturbances.

Early Cataract Sign 2: Is Your Entire Field of Vision Hazy, Not Just Near Vision?

Presbyopia primarily impairs near vision, making small text on smartphones appear blurry. However, if you experience an overall drop in visual clarity regardless of distance, crystalline lens degeneration should be suspected. If everything looks hazy (as if looking through a fogged window), a comprehensive eye examination is recommended.

Early Cataract Sign 3: Are You Experiencing Foggy Vision Accompanied by Glare?

Opacity in the crystalline lens creates an irregular path for incoming light. As light scatters irregularly, halos may appear around light sources, or you may experience severe glare. If you notice significant light scattering from oncoming headlights during night driving, it is vital to evaluate the condition of your natural lens.

Early Cataract Sign 4: Do Colors Appear Dull or Yellowish Compared to Before?

Cataracts also affect color contrast sensitivity. White objects may appear yellowish, or the world in general may seem dull and dark. If others frequently comment that you set your screen brightness unusually high, there is a strong possibility that the transparency within your eyes has declined.

Early Cataract Sign 5: Frequent Eyeglass Prescription Changes Without Visual Clarity

When refractive power shifts due to lens opacity, your vision may remain unsatisfactory even after updating your prescription multiple times in a short period. Notably, if someone who previously relied on reading glasses suddenly finds near text easy to read, this is rarely an improvement in sight, it is typically a paradoxical refractive shift caused by progressing cataracts.

Early Cataract Sign 6: Rapidly Increasing Eye Fatigue and Headaches

When your brain continuously attempts to compensate for and clarify blurry images, it consumes excessive neural energy. If your concentration wanes quickly, or if you frequently experience dull headaches and aching around the eyes, consider the possibility of visual stress caused by crystalline lens dysfunction.

A Professional Examination Is Necessary If These Symptoms Persist

  • TV subtitles or printed text appear overlapped or double
  • Halos and light diffusion spread around streetlights or car headlights during night driving
  • Object outlines appear blurry or split into two even when viewing with a single eye
  • Your vision remains dim or hazy despite updating your eyeglass prescription multiple times in a short timeframe
  • Overall color perception appears dull, as if viewing through a yellow filter

Timing Cataract Surgery and Selecting the Right Intraocular Lens (IOL)

Opacity in the natural lens does not clear up on its own. When visual impairment significantly impacts your daily life, surgical intervention to replace the clouded lens with an artificial intraocular lens (IOL) should be considered. Since options range from monofocal and multifocal to toric (astigmatism-correcting) lenses, selecting the lens best suited to your personal lifestyle is key to post-operative satisfaction.

Healthy Eye Care Begins with Accurate Diagnosis

Rather than dismissing vision changes as a normal part of aging, establishing a preventative care plan through routine eye checkups is essential. BGN Eye Clinic at Jamsil Lotte Tower is always here to safeguard your precious sight.
