# What is a chemical eye burn?

A chemical eye burn occurs when irritant, acidic, or alkaline substances contact the ocular surface and damage the cornea and conjunctiva. Alkali burns are particularly dangerous because they penetrate tissues rapidly.

## Immediate Effects

Patients experience sudden pain, redness, watering, light sensitivity, and blurred vision; severe burns can whiten the conjunctiva and cornea, indicating deeper injury.

- Common household sources include cleaning agents, bleach, ammonia, and cement.
- Industrial accidents may involve strong alkalis, acids, or solvents.
- Severity depends on chemical type, concentration, volume, and contact time.
- Prompt irrigation is the single most important first aid step.

## Treatment and Risks

Urgent, copious irrigation with water or saline followed by emergency ophthalmic assessment is essential to limit damage and preserve sight.

- Ongoing care may include topical antibiotics, steroids, lubricants, and sometimes amniotic membrane grafts or limbal stem cell transplantation.
- Complications include corneal scarring, limbal stem cell failure, glaucoma, and dry eye.
- Protective eyewear in high‑risk settings greatly reduces the chance of chemical burns.
- Long‑term follow‑up is often required because surface problems and scarring can evolve over months.
