Virtual entities are displayed alongside real world entities in a wearable reality overlay device worn by the user. Information related to an environment proximate to the wearable device is determined. For example, a position of the wearable device may be determined, a camera may capture an image of the environment, etc. Virtual entity image information representative of an entity desired to be virtually displayed is processed based on the determined information. An image of the entity is generated based on the processed image information as a non-transparent region of a lens of the wearable device, enabling the entity to appear to be present in the environment to the user. The image of the entity may conceal a real world entity that would otherwise be visible to the user through the wearable device. Other real world entities may be visible to the user through the wearable device.
