Typically, the eyelids react to a threat by closing quickly to protect the eyes from harm. However, chemicals can still sometimes reach the eye if the lids don't close quickly enough. Chemicals may be in liquid or powdered form and can cause irritation and burns.
The most dangerous chemicals are strong acids or alkali. Alkali burns tend to be more serious than burns from acid. Alkali chemicals include lye, concrete, mortar, oven and drain cleaners, dishwasher detergent, and fertilizers.
A chemical splash in the eye requires immediate medical help. Seek emergency care by an eye specialist (ophthalmologist) or call 911 or your local emergency number. Take the chemical container or the name of the chemical with you to the emergency provider. If readily available, wear sunglasses to help reduce sensitivity to light.
If a chemical splashes into your eye, take these steps immediately.
