What is meant by dazzling in the context of light?

A very dim light
A light that emits color
A light so bright it can temporarily blind you
A flickering light

The correct answer is: A light so bright it can temporarily blind you

Dazzling, in the context of light, refers to an intensity that is exceptionally bright, often to the point of overwhelming the observer's eyes and causing temporary blindness or difficulty in seeing clearly. This phenomenon typically occurs when a source of light is so intense that it exceeds the threshold of comfort for the human eye, resulting in a blinding effect. In nature, examples of dazzling light can be seen in very bright sunlight or when staring directly at a bright light source, such as headlights or flash photography. Since dazzling light can impede one's ability to see for a moment, it encompasses the concept of brightness associated with discomfort or impairment of vision, making this interpretation the most fitting in this context.
