Visual Fatigue Cause-Based Management / 视疲劳病因导向管理

Definition

Visual fatigue cause-based management is the episode’s framework for treating tired or uncomfortable eyes as a symptom with several possible ocular, optical, and behavioral causes rather than as one disease solved by one eye drop.

Current Synthesis

The source separates the experience of eye fatigue from its mechanism. Sustained near focus, reduced blinking and dry eye, inaccurate correction of myopia, hyperopia, astigmatism or presbyopia, accommodation problems, and conjunctival or corneal inflammation can overlap while requiring different responses. A green background does not relax accommodation merely because distant greenery feels comfortable; viewing distance, contrast, rest, refraction, and examination matter more than color symbolism.

The practical sequence is therefore cause first, intervention second. Simple artificial tears may help a dry-eye pattern, while optical causes call for accurate refraction and suitable correction, and persistent, painful, inflamed, or changing symptoms require clinical assessment. Eyelid twitching is adjacent but not identical: brief episodes may follow fatigue or poor rest, whereas persistent twitching is not resolved by routine eye drops and may require broader evaluation.

Key Claims

  • “Eye fatigue” is a symptom category with dry-eye, refractive, accommodative, inflammatory, and behavioral branches.
  • Screen color alone does not reproduce the relaxation associated with looking far away.
  • Artificial tears may relieve a dry-eye contribution but are not a universal treatment for fatigue.
  • Accurate refraction and suitable correction matter when myopia, hyperopia, astigmatism, or presbyopia increases effort.
  • Contrast, resolution, flicker, viewing distance, duration, and ambient light can change comfort without diagnosing the cause.
  • Persistent symptoms, inflammation, vision change, or prolonged eyelid twitching require assessment beyond generic self-care.

Evidence

  • Cause separation - VOL.38 distinguishes dry eye, refractive or accommodation problems, conjunctivitis, keratitis, and post-surgical age-related factors.
  • Distance and contrast - VOL.38 says distant viewing rather than the color green produces the main relaxation effect and warns that poor contrast may add fatigue.
  • Treatment matching - VOL.38 limits simple artificial tears to some dry-eye cases and directs refractive causes toward accurate testing and correction.
  • Eyelid-twitch boundary - VOL.38 separates short fatigue-linked twitching from prolonged twitching that may require non-ophthalmic assessment.

Counterevidence & Qualifications

The source does not provide a diagnostic algorithm, validated symptom scale, examination findings, or comparative evidence for screen settings and devices. Fatigue may coexist with disease, and apparently ordinary discomfort should not delay care when pain, marked redness, light sensitivity, discharge, trauma, persistent headache, double vision, or new visual change is present. Eye drops, glasses, device settings, and referrals remain individualized.

What Changed

  • Created a cause-first framework separating visual-fatigue symptoms from dry-eye, refraction, accommodation, inflammation, and screen context.
  • Added a boundary against treating green backgrounds or generic eye drops as universal solutions.
