Visual haze
Visual haze can be described as an effect which distorts the surrounding environment to make it appear as if the air is shrouded in an imaginary cloud of smoke, fog, or haze. This effect varies in its intensity, ranging from subtle and barely visible to extreme and all-encompassing to the point of significantly impairing one's vision.
Visual haze is most commonly induced under the influence of mild dosages of hallucinogenic compounds such as psychedelics, deliriants, and cannabinoids. However, it can also occur less commonly under the influence of stimulant psychosis and sleep deprivation.
