Eye wash refers to a liquid solution formulated to rinse and cleanse the eyes. It is a medical product specifically designed for emergency situations where the eyes have been exposed to harmful substances, such as chemicals or foreign particles. Eye wash solutions are typically sterile and isotonic, meaning they have the same salt concentration as the fluids in the eyes, to ensure minimal discomfort and damage during use.
The primary function of eye wash is to flush out any irritants or contaminants that may have entered the eyes, providing immediate relief to the affected individual. It works by effectively removing the harmful substances, diluting them in order to prevent further damage, and facilitating the body's natural healing process. Eye wash solutions are commonly used in industrial and laboratory settings, where the risk of eye exposure to hazardous materials is high.
Eye wash solutions are frequently available in portable bottles or stand-alone stations, equipped with a nozzle or eyecup for ease of application. It is recommended to follow specific instructions for proper usage, including the duration and direction of rinsing. Eye wash is not intended for prolonged use and should only be utilized as an initial response to eye contamination, as it does not replace professional medical treatment or assessment.
Overall, eye wash is an essential tool in maintaining eye health and preventing further damage from contaminants, providing immediate relief and allowing for the successful treatment of eye-related emergencies.

The term "eye wash" has a literal and a figurative meaning.
Literally, it refers to a liquid solution used for rinsing and cleaning the eyes, often used to relieve irritation or remove foreign objects. The etymology of this term can be traced back to the Middle English word "eyewoche", which was derived from the Old English word "ēagwōce". "Ēage" meant "eye" in Old English, and "wōce" referred to a medicinal lotion or eye treatment. Over time, "eyewoche" transformed into "eyewash" and eventually the modern term "eye wash".
Figuratively, "eye wash" is used to describe something insincere or false, typically used to deceive or mislead.
