- Dark adaptor goggles, also called red adaptation goggles, are used in the field of meteorology and astronomy for adapting the eyes to the dark prior to an observation at night. They also aid with the identification of clouds during bright sunshine or glare from snow. The goggles are made with red-tinted plastic lenses. Such goggles or glasses are often used by pilots and weather observers to preserve their natural night vision. To help with the identification of clouds during the day, the goggles should be put on just before the observer goes outside. This will ensure the eyes are not affected by the glare from the sun or snow. For use at night, the observer should put the goggles on about ten minutes prior to going outside. Once the observer is outside and away from major sources of light, the goggles may be removed and the observer's vision should be adapted to the dark. Although the goggles are designed to be worn indoors, some people find walking around inside, especially up and down stairs, to be difficult. At no time should the goggles be used to help assess the visibility. (en)
- Les lunettes d'obscurité sont un type particulier de lunettes de protection qui permettent à l'utilisateur d'ajuster sa vision à la faible luminosité nocturne. Elles sont particulièrement utilisées par les techniciens pour prendre les mesures de visibilité aux stations météorologiques ou pour diminuer les reflets lors de l'observation des nuages par journée ensoleillée. Elles ont été inventées en 1916 par un physiologiste allemand, Wilhelm Trendelenburgen, pour être utilisées en fluoroscopie (fr)
