Without objects to reflect the light, we do not see the light.

When I look at a book, for instance, I see the book sitting on the shelf. I do not see the light travelling from the book.

If I shine I light in the dark, I see the light reflecting off the object the light shines on. But I do not see the light travelling between me and the object. I will see it if there are particles like dust or smoke in the air between me and the object. But if there are no objects in the air to reflect the light I do not see the light.

If I stand to the side of you I do not see light entering your eyes.

Good thing we don't see it too. Otherwise we'd be walking around in a color light fog.
