What does eyewash mean?
Eyewash is a compound noun with two distinct senses. Its literal meaning is a liquid preparation — often sterile saline or a medicated rinse — used to flush or soothe the eyes, familiar from first-aid kits, laboratories, and workplace safety regulations. Its figurative meaning, chiefly in British English, is sharply different: eyewash denotes empty, misleading, or deliberately deceptive talk, such as official statements issued to give a false impression of competence or concern. In this use it carries a dismissive, sceptical tone and sits alongside terms like hogwash and humbug. The figurative sense likely plays on the idea of something applied superficially — a gesture that rinses over problems without treating them. Both senses are well established: the literal one in medical and industrial contexts worldwide, the figurative one as a colourful staple of British informal speech.
A liquid preparation used to rinse, cleanse, or soothe the eyes.
"Flush the affected eye thoroughly with sterile eyewash before seeking medical attention."
(British English, informal) Deceptive or meaningless talk intended to create a false impression; empty gestures presented as genuine action.
"Critics condemned the consultation exercise as eyewash, noting that the decision had already been made."
Informal and chiefly British; dismissive in tone.
Rarely pluralized. In the figurative sense eyewash functions as an uncountable mass noun, so no plural form is used. The plural appears only occasionally for the literal sense, referring to different types or bottles of eye-rinsing solutions.
"The pharmacy stocked several medicated eyewashes for allergy sufferers."
In Britain, calling a report 'eyewash' doesn't mean it made you cry — it means someone tried to pull the wool over your eyes.

Etymology of eyewash
Eyewash is formed transparently from the nouns 'eye' and 'wash', following the pattern of other wash-based compounds such as whitewash and brainwash. The literal sense — a lotion for cleansing the eyes — dates back several centuries in English. The figurative sense of deceptive talk developed later, apparently from the notion of a superficial application meant to mask rather than cure, and became established in informal British usage during the twentieth century.
How eyewash is actually used
The literal sense is standard in both American and British English, common in medical and workplace-safety contexts. The figurative sense is chiefly British and distinctly informal, carrying a dismissive, mildly cynical tone; it usually implies deliberate deception dressed up as officialdom or sincerity rather than simple nonsense.
