Why Can Dry Eyes Still Water?
An ineffective tear film can irritate the ocular surface and provoke extra reflex tears. More tears do not always restore stable coverage, and watery eyes can have several causes. This is one possible response, not a diagnosis.

What the illustration shows
Navy-and-gold educational poster titled “Why Can Dry Eyes Still Water?” A left-eye close-up shows the nose at left, a peach tear gland above the outer corner at right, and a tear below the lower eyelid. A gold surface target leads to two enlarged views: a smooth blue tear film over intact peach surface cells, and an uneven blue film over another intact surface. Leaders label tear film, eye surface and uneven coverage. Text states that film thickness is exaggerated and the surface remains intact in this schematic. A lower strip uses dashed gold arrows from unstable tear film to surface irritation to extra reflex tears, explicitly a simplified reflex rather than tear flow. Takeaways say more tears do not always mean a stable tear film and watery eyes have more than one cause. “Illustration not to scale,” gold AllHumanBody.com and the full project slogan appear on plain navy below.
How to interpret this poster
- Film thickness and irritation symbols exaggerated; not a measured neural tract. Intact surface in this schematic does not mean dry-eye disease never damages tissue; no treatment advice.
- 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.
