Zatemující

Zatemňující is a Czech adjective and present participle formed from the verb zatemnit, meaning to darken or obscure. The term describes something that reduces the transmission of light or visibility, producing a darker appearance or increased privacy. It is commonly used for materials, coatings and devices designed to limit light or visibility.

Common usages include zatemňující závěsy (blackout curtains) and zatemňující rolety (darkening blinds) used to block sunlight in interiors. In optics and photography, zatemňující filtry or zatemňující sklo reduce brightness; tinted glass used in cars and buildings is often described as zatemňující. Eyewear such as zatemňující brýle (sunglasses) lowers glare. In media production, zatemňující efekty refer to techniques that darken parts of a scene.

Grammatical notes: zatemňující is used as a present participle and can function as an attributive adjective with nouns of any gender. Its past participle form, zatemněný, describes something that has already been darkened, and zatemnění denotes the act or result of darkening.
