1. Why binoculars?

Apparently binoculars seems to be a poor optical instrument. Any average astronomical telescope can gain higher magnification and thanks to a big lens is able to gather more light. Fortunately, considering binoculars, magnification is not the most important thing. In this case we deal with a compromise between reasonable magnification and lens diameter, where important is size, which can’t be too big so that we could use it in specific conditions. Why binoculars are just so amazing instrument? Answer may be short and surprising as well. This instrument is just chosen by the nature in the course of long evolution. Our eyes are nothing else but perfect binoculars with 1x7 parameters. It truly is an excellent equipment featured by a wide angle of view, a smooth focusing, a great image stabilization and self-cleaning. But it has a one disadvantage: sometimes it breaks down. On the other hand would you be able to show me an optical instrument which works perfectly and which doesn’t get worse in the course of time.
