A reflex sight is provided, including a first lens module, a first light source, and a second light source. The first light source projects a first reticle image to the first lens module, and the first lens module reflects the first reticle image to a viewer. When the first light source is inactive, the second light source projects a second reticle image to the first lens module, and the first lens module reflects the second reticle image to the viewer.
