'''Binoculars''' is an optical aide used to view distant objects with both eyes, such as scenery, wildlife, far off boats / ships & basic Astronomy (if you can't quite afford a Telescope).

'''Binoculars''' are an [[optics|optical]] aid used to view distant objects with both [[eye]]s, such as scenery, wildlife, or far off boats or ships.  They can also be employed in basic [[astronomy]], in lieu of a [[telescope]].

 

They consist of twin barrels containing various [[lens]]es, one for each eye.  These are hinged together so the binoculars can be adjusted to fit the user's eyes.  A focusing knob is usually provided in the center to focus both sides at the same time.

 

While most binoculars are simply designed to be purely functional, opera glasses are a kind of binoculars that are usually rather [[ornate]] in finish.  They are used to improve the patron's view of the action on [[stage]].  The fancy form fits in with the formal nature of a performance and the highly decorated interior of most [[theater]]s.
