Here are a few options:

* A light source: This is the most obvious answer. You can see a light source in darkness because it emits light, which then travels to your eyes. Examples include:

* A lamp

* A star

* A firefly

* A phone screen

* Objects illuminated by a light source: Objects that reflect light from a source can also be seen in darkness. The brightness of the object depends on how much light it reflects and the intensity of the light source. Examples include:

* A person standing in the light of a streetlamp

* A cat's eyes reflecting car headlights

* A white wall illuminated by a flashlight

* Objects that emit their own light: Some objects, like certain types of mushrooms, phosphorescent materials, and some animals, emit their own light through bioluminescence. This light can be seen in darkness without relying on a separate source.

* Objects using night vision: Even though the human eye can't see well in the dark, technology like night vision goggles can amplify available light, making it possible to see objects in near darkness.

So, it really depends on what you're looking for!
