Light Sensitivity (Photophobia)

How Chinese medicine differentiates light sensitivity into the six patterns you'll actually meet in practice, and the points for each. Acupuncture only — no herbs.

This page is educational, for practitioners and students — it is not a diagnostic tool and does not replace a proper in-person assessment. Sudden light sensitivity with severe eye pain, vision loss, or a severe headache needs prompt medical evaluation before assuming a simple pattern.
General Acupuncture Points

Acupuncture points traditionally used for light sensitivity — 8 key points, used across the patterns below rather than tied to just one.

LR-3 ↓ G.B.-20 ↓ EX-HN-5 (Taiyang) ↓
Note: no moxa. Direct exact-name match with this site's own Liver-Yang-rising slide. EX-HN-5 (Taiyang) has no dedicated location page on this site, shown as a nolink chip.

3. Wind-Heat View full pattern →

Clinical manifestations: Sudden onset of red, burning, tearing eyes, sore throat and mild fever or chills (more fever than chills).
Tongue: Red tip and edges with thin yellow coating. Pulse: Floating and rapid.
Treatment principle: Disperse Wind-Heat, clear Lung Heat, cool and soothe the eyes.
L.I.-4 ↓ G.B.-20 ↓ EX-HN-5 (Taiyang) ↓ BL-1 ↓
Note: no moxa. Matched to this site's own Invasion-of-Lungs-by-Wind-Heat slide on the exterior-invasion level, the same convention used for several other Wind-Heat-driven eye conditions.

4. Liver Yin Deficiency View full pattern →

Clinical manifestations: Dry, gritty, sandy sensation in the eyes, blurred vision worsening with prolonged use, sensitivity to light, night sweats, feeling of heat in the palms/soles/chest.
Tongue: Red body (especially sides) with little or no coating, dry shiny surface. Pulse: Wiry, fine, rapid.

Tongue: Red body with redder sides, yellow greasy coating (thicker at the center and root). Pulse: Wiry, slippery, rapid.
Treatment principle: Drain Damp-Heat from the Liver and Gallbladder, clear the thick turbid steam rising to the eyes.
Note: no moxa. This site's Damp-Heat-in-the-Liver slide is genital/vaginal-discharge-specific, confirmed by re-reading its content — not a fit for an eyelid/discharge presentation, consistent with the same finding on Keratitis and Ptosis earlier this project — no pattern link is given here; points still link fine individually.

6. Qi and Blood Deficiency

Clinical manifestations: Dull, persistent (not sharp/burning) light sensitivity, pale complexion/lips/nail beds, severe fatigue worsening with overexertion, blurred vision improving with rest, poor appetite and loose stools.
Tongue: Pale body (may be thin with teeth marks on the edges), thin white coating. Pulse: Fine and weak.
Treatment principle: Tonify Qi and Blood, strengthen the Spleen, restore resilience to light.
ST-36 ↑ SP-6 ↑ EX-HN-5 (Taiyang) ⊥
Note: moxa applicable on ST-36/SP-6. This site has no combined Qi-and-Blood-deficiency slide, a gap confirmed absent many times over — no pattern link is given here; points still link fine individually.
