How are we able to see light sources?

We are able to see light sources because they emit light, which travels through space and enters our eyes. The light then interacts with the photoreceptor cells in our retinas, triggering a signal that is transmitted to our brain, where it is processed into an image. Additionally, our ability to perceive light sources is influenced by factors such as distance, intensity, and the presence of objects that may reflect or refract the light.
