Medicines for Chemical eye injury

What it is

A chemical eye injury happens when a chemical substance splashes or gets into the eye — for example household cleaners, bleach, drain or oven cleaners, DIY chemicals, industrial substances, or even some cosmetics. It is a medical emergency because certain chemicals, particularly strong alkalis (such as those in some cleaning products, cement and plaster) and strong acids, can rapidly damage the surface of the eye and, if not treated immediately, threaten sight. Symptoms include immediate pain, stinging or burning, watering, redness, blurred vision, and difficulty opening the eye. The single most important factor in the outcome is how quickly the chemical is washed out of the eye — immediate and prolonged rinsing dramatically reduces the damage. This is one of the few situations where taking action yourself, before getting to medical help, is critical and can save the eye.

How it is treated

The immediate action is to rinse the eye with water straight away and keep rinsing — this is the priority, before anything else. Hold the affected eye open (or have someone help) and flush it continuously with clean, lukewarm water (or a sterile saline solution if available) for a prolonged period — commonly at least 15–20 minutes — allowing the water to run across the eye from the inner corner outwards, and removing contact lenses if worn. It is important not to rub the eye, and not to try to neutralise the chemical with another substance — just rinse thoroughly with water. While or after rinsing, seek urgent medical help — going to an eye casualty or A&E, or calling for advice — and take the chemical container or details if possible, as the type of chemical guides treatment. Medical treatment continues the rinsing, checks the eye's acidity, and treats the injury to protect the eye and vision. The overriding message is: for any chemical in the eye, rinse immediately and copiously with water, then seek urgent care — acting fast can save sight.
