Category Advice

Binoculars are like two telescopes mounted side by side. So, how do telescopes work? At the front of each telescope is a lens�either an objective or a field lens. This gathers light from whatever it is you’re looking at. Let’s says you're looking at a bird. The objective or field lens magnifies the image of the bird, but this image is upside-down. Not very useful at this point. If you’re using prism binoculars (and most likely you are�they’re the most popular kind), a prism in each tube reverses and inverts the image of the bird. In field glasses, there’s a second lens instead of a prism. The light then travels down the tube, and through a lens in the eyepieces. The bird is magnified even further. Good binoculars will give you an accurate and detailed look at the bird.
