If you want to know about my eyes, check this out.

Astigmatism occurs when an irregularly shaped cornea creates multiple focal points, causing blurry or doubled vision. Trying to force your eyes to focus without proper correction can lead to eye strain, persistent headaches, and shoulder stiffness.

Do You Experience These Symptoms?

BLURRY
Blurred, shadowed, or overlapping vision

EYE STRAIN
Frequent eye fatigue, dizziness, or headaches

NIGHT VISION
Difficulty driving at night due to glare and halos

FOCUS
Unclear focus even when wearing regular glasses or lenses

Interesting Self astigmatism test

Curious if you might have astigmatism?
Check these quick tests!

  • Test ① (Line Pattern): If all lines appear equal in thickness, your vision is likely normal. If certain lines look darker, thicker, or distorted, you may have astigmatism.

  • Test ② (Number Image): Look at the optical illusion image. Seeing 1240 indicates normal vision, while seeing 3246 or 3240 suggests potential astigmatism.

    (※ Note: These tests are for simple reference only and do not constitute medical advice. Please consult an eye care professional for an accurate eye exam.)

Quick Checklist Before Ordering

  • Required Prescription Info: Please enter your SPH, CYL, and AXIS for both left and right eyes separately.

  • Fixed Specifications: DIA (Overall Diameter) and G.DIA (Graphic Diameter) are fixed for each design.

  • Standard 8.6mm Base Curve (BC): Designed based on vast eye curvature data. A slight variation of ±0.2mm (e.g., BC 8.7mm) will still fit comfortably.
