# Eye

Use the eye to view an object marker or its image (whether real or virtual). The eye consists of an eye part and a display screen, where the picture the eye 'sees' is displayed.

Tips for use:

- The eye can only be used to view objects and images associated with ray diagram simulation. It will not interact with general light sources such as rays and beams, nor can it 'see' other parts in the optical space.
