Translucent Red Luminocular
The concept of binoculars is almost as old as the telescope, developed in the 1600s to magnify far away objects. Essentially, binoculars are composed of two telescopes next to each other, allowing the viewer to perceive depth.
By using two convex lenses, telescopes help focus light from far away objects, allowing a viewer to see distant items up close. A binocular simply takes this idea and doubles it, so that both eyes can be used.
