What does eyebath mean?
An eyebath is a small, cup-shaped vessel designed to hold water or a cleansing solution against the open eye so that the liquid can rinse away dust, irritants, or discharge, or simply soothe tired eyes. The user fills the cup, bends forward, presses its rim around the eye socket, then tips the head back briefly so the fluid bathes the eye before draining it out. Eyebaths have long been a fixture of household medicine cabinets, particularly in Britain, where they are commonly sold in pharmacies alongside eyecups and sterile washes. In clinical settings the practice is usually described as eye irrigation and performed with specialised equipment, but at home the eyebath remains a simple, inexpensive tool for minor eye care. The word itself is an obvious compound of 'eye' and 'bath', coined from the familiar notion of bathing a body part in liquid.

Etymology of eyebath
The word 'eyebath' is a straightforward English compound formed from 'eye' and 'bath', both ancient words of Germanic origin: 'eye' traces back to Old English 'ēage', and 'bath' to Old English 'bæth', from Proto-Germanic roots. The compound arose as part of the productive pattern of combining 'bath' with body parts, on the model of terms like 'footbath'. It appears to be a relatively modern coinage, becoming common alongside commercial eyecup products in the nineteenth and twentieth centuries.
