The Dark adaptor goggles are one of the lesser known tools in the field of meteorology. They can be used for either adapting the eyes to the dark prior to an observation at night or to aid with the identification of clouds during bright sunshine or glare from 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 observers vision should be adapted to the dark.
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. Glare may refer to either of the following: A call collision in telecommunications. ...
At no time should the goggles be used to help assess the visibility. In meteorology, visibility is a measure of the distance that can be seen clearly at any given time. ...
