Fechner's Paradox (health)


The fact that a monocular view may look brighter than a binocular view. Suppose that a scene is viewed through both eyes but that one eye sees it through a neutral filter that attenuates all wavelengths by a constant ratio. The filter does not distort the reflectances or ratios of light reaching the eye, but only its absolute intensity. If the filtered eye is entirely occluded the scene looks brighter and more vivid than with the filter despite the fact that less total light is reaching the two eyes and the reflectances are still the same.
