Wimpers

Wimpers, in English more commonly called eyelashes, are the short, curved hairs that grow along the margins of the upper and lower eyelids. They form a protective barrier for the eyes by helping to trap dust and debris and by triggering blinking in response to tactile stimulation at the lash line.

Anatomy and growth: Each lash grows from a follicle embedded in the eyelid skin. The upper eyelid typically has more numerous and longer lashes than the lower lid. Lash density, length, and curl vary among individuals and are influenced by genetics, age, and hormonal factors. Hairs on the eyelids go through a cyclical growth process—anagen (growth), catagen (transition), and telogen (rest). At the base of each lash are small glands, including sebaceous glands associated with the hair follicle, that help lubricate the lash area.

Function: Wimpers provide a protective function by reducing the amount of foreign material reaching the ocular surface and by triggering reflex blinking. They also contribute to sensory perception around the eye and may influence the microenvironment near the eye by filtering light and air flow to a limited extent.

Care, cosmetics, and clinical relevance: People commonly cleanse the eye area gently and avoid rubbing eyelids. Cosmetic products, such as mascara and eyelash curlers, are widely used; false eyelashes and extensions are popular but can cause irritation or lash damage if misapplied. Medically, lash-related issues include madarosis (loss of lashes), trichiasis (misdirected lashes rubbing the eye), and blepharitis. Growth-promoting treatments exist but may carry side effects.

Linguistic note: The term wimpers is Dutch for eyelashes; in English, the standard term is eyelashes.
