Why Does Pink Eye Look Red?

READ THE IMAGE

What the illustration shows

Educational poster titled “Why Does Pink Eye Look Red?” on a navy background. A large oblique eye view shows a blue-and-gold iris and black pupil behind a clear corneal dome. Fine red vessels branch across the white scleral surface but do not cross the cornea. A small transparent conjunctival flap is lifted to reveal its location; a partial upper eyelid shows the inner lining. White leaders identify conjunctiva, sclera, small blood vessels, clear cornea and inner eyelid lining. Two lower translucent-tissue closeups contrast narrower and enlarged red vessel networks over ivory support. Text says inflammation can enlarge conjunctival vessels and prominently warns, “Not every red eye is conjunctivitis.” A small note identifies schematic enlargement, not to scale, and anatomy education, not diagnosis. Gold AllHumanBody.com and the full slogan appear on the plain navy footer.

How to interpret this poster

• No cause assigned from redness, reassurance, subtype chart or treatment advice. Enlarged caliber is qualitative; iris is not described as avascular.
• AI-assisted educational illustration; not physician certification, a diagnosis or individualized medical advice.
• Fine annotations require enlargement; preserve the full uncropped illustration and its qualifiers.
