Dark adaptor goggles are goggles made with red-tinted plastic lenses. Dark adaptor goggles were invented by Wilhelm Trendelenburg in 1916. [1] The concept is based on the work by Antoine Béclère on dark adaptation of the eye, where it is noted that fluoroscopy relies on the use of the retinal rods of the eye.

Chromatic adaptation is the human visual system’s ability to adjust to changes in illumination in order to preserve the appearance of object colors. It is responsible for the stable appearance of object colors despite the wide variation of light which might be reflected from an object and observed by our eyes.
Dark adaptation of both rods and cones requires the regeneration of the visual pigment from opsin and 11-cis retinal. [13] Therefore, the time required for dark adaptation and pigment regeneration is largely determined by the local concentration of 11-cis retinal and the rate at which it is delivered to the opsin in the bleached rods. [14]
“This is an example of ‘know thy neighbor’ and those neighbors were able to help prevent this child from being permanently taken,” Hallandale Beach Police Capt. Megan Jones told NBC 6.
Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...
