Caffeine might slightly increase tear production in some people, but it is not a primary treatment for dry eyes.
Caffeine and the tear film
Research suggests caffeine can stimulate certain glands, including those involved in tear production. However, the effect is modest and may vary between individuals.
- Some people notice no change in symptoms with caffeine
- Too much caffeine can disturb sleep, which may worsen eye strain
- Caffeinated drinks with sugar can contribute to general dehydration
- Dry eye still needs proper assessment and tailored treatment
Better ways to manage dry eye
Relying on caffeine alone is not recommended. Evidence-based treatments focus on lubricating drops, eyelid care, and addressing lifestyle or medical factors.
- Use preservative-free artificial tears regularly as advised
- Practice warm compresses and lid hygiene if meibomian glands are involved
- Discuss prescription treatments or plugs with your specialist if symptoms persist
- Keep hydrated and take regular breaks from screens
