More recently binoculars have been used for astronomical viewing. The optics field is quite large and the number of products is considerable.
Monoculars permits the use of only one eye to view the articles which causes some problems. If you are going to use the binoculars yourself go for a higher quality optics which naturally would cost more. Compact binoculars have a very small objective lens, and this feature makes them user friendly.
Attached caps will protect the lenses, but not require you to fumble in your pockets looking for lens caps if it starts to rain or snow. Viewers can use a pair of binoculars for bird watching, star gazing, observing far off animals, spotting ships at sea, watching a concert, or enjoying a sports game from a nosebleed seat. Magnification over ten generally causes the binoculars to lose some image crispness.
Low light uses such as hunting, birding and astronomy require larger objective lenses. Ideally, you are going to lug these babies around for 10 or 20 years, so get a good pair.
