Redness is a reaction to smoke and airborne particles. Mild eye irritation after Diwali may subside when exposure ceases. But if you have persistent or worsening redness you should see a health care professional.
Redness that is painful, blurred vision or light sensitivity is a sign of corneal injury or inflammation. Also conditions like iritis may cause pain in the red eye and appropriate iritis treatment requires an ophthalmologist’s diagnosis.
2. Burning, Grittiness or Excessive Watering
Smoke, ash, and dust may cause tear film disturbance and irritate corneal and conjunctival surfaces. Eye may feel gritty, dry, burning or extra watery. Post Diwali eye symptoms may be due to surface irritation, but persistent discomfort should be checked out by an eye care professional. Also in the Vasan guide to red eye causes they discuss that redness has many different causes.
| Symptom | Possible explanation | Suggested urgency |
| Mild burning or watering | Smoke or surface irritation | Monitor; seek care if persistent |

| Severe pain | Corneal or deeper eye injury | Urgent assessment |
| Sudden blurred vision | Trauma or internal eye damage | Urgent assessment |

| Visual acuity | Clarity of vision | Detects reduced vision |
| Slit-lamp examination | Cornea and front of eye | Identifies abrasions or inflammation |
| Dilated examination | Retina and internal structures | Checks deeper injury |
| Eye-pressure measurement | Intraocular pressure | Detects pressure abnormalities |
6. New Floaters, Flashes or a Curtain-Like Shadow
New floater issues, flashes of light or a dark curtain in your field of vision are post Diwali eye symptoms which require urgent assessment especially after an injury. They may be a sign of damage to the vitreous or retina.
