Chest pain, breathlessness, or severe symptoms? Seek urgent care — First Aid guides · Warning signs

Red or pink eyes can range from a minor irritation to a sign of a serious condition. Most causes are mild and manageable at home, but some require prompt medical attention.

Common Causes

  • Conjunctivitis — viral, bacterial, or allergic
  • Eye strain from prolonged screen time
  • Dry eyes — insufficient tear production
  • Allergies — dust, pollen, pet dander
  • Contact lens irritation or overuse
  • Broken blood vessel (subconjunctival haemorrhage) — usually harmless
  • Foreign body in the eye
  • Lack of sleep
  • Glaucoma — raised eye pressure (emergency if sudden)

Home Care and Relief

Cold or warm compress

For viral or allergic conjunctivitis, a cool damp cloth over closed eyes reduces inflammation. For eye styes, a warm compress helps open blocked glands.

Saline eye wash

Rinse with sterile saline to flush out irritants, allergens, or discharge. Especially helpful for allergy-related redness.

Cucumber slices

Cool cucumber slices over closed eyes for 10–15 minutes reduce puffiness and redness from strain.

Rose water

A few drops of pure sterile rose water soothes mild redness. Ensure it is medical-grade.

20-20-20 rule

Every 20 minutes, look at something 20 feet away for 20 seconds. Take a full break every 2 hours. Most effective for screen-related redness.

Avoid rubbing

Rubbing introduces bacteria, worsens irritation, and can scratch the cornea. Use a cold compress instead.

Artificial tears

Preservative-free artificial tear drops for dry eye redness. Avoid drops that promise to ‘get the red out’ — they cause rebound redness.

Remove contact lenses

Remove immediately when eyes become red. Do not reinsert until redness fully resolves.

When to See a Doctor

  • Sudden severe eye pain — possible glaucoma emergency
  • Vision changes: blurring, double vision, or loss
  • Eye redness after injury or chemical splash
  • Yellow or green discharge — bacterial infection
  • Redness with significant light sensitivity and pain
  • Redness not improving within 48–72 hours
  • Something stuck in the eye that cannot be flushed out
