Does condensation increase light glare?

Condensation does indeed increase light glare. When moisture condenses on surfaces, such as windows or lenses, it creates a layer of water droplets that can distort light passing through. This distortion causes the light to scatter, leading to an increase in glare, which can be particularly distracting or even hazardous while driving. This effect is most pronounced when light sources, such as headlights from vehicles or streetlights, are present, as the droplets cause the light to disperse in various directions.

Though other factors like temperature or the intensity of lights can influence visibility, the fundamental effect of condensation is that it alters how light travels, intensifying glare regardless of specific conditions or scenarios. This is why understanding the impact of environmental conditions like condensation is crucial for safe driving practices.
