In daily life, optical telescopes usually showed a tubular optical instrument, it is refracted through the lens, or reflected by concave mirror to focus light directly imaging, or go through a magnifying eyepiece for observation. Optical telescope in daily life, also known as "thousand mirrors." It is mainly an amateur telescope, opera binoculars and military binoculars.

Binocular glasses are a pair of identical or mirror-symmetrical telescopes, allowing the viewer to use both eyes to see distant objects clearly. Unlike monocular telescope, binoculars give users a three-dimensional image. Therefore, they are referred as the best created wonders of science.They are created by Johannes Buttgenbach, who just added lens of a binocular to normal glasses to achieve image captured in distance. The binocular glasses, since their first inception, became the focus of global attention and then were patented in the United Stages and Europe by Johannes and began to be sold on the market.

Mostly made in German, binocular glasses are of high quality and are featured with light weight, so they are favoured with the pubic. People can wear them to watch football games, and anything that you want to see but is not visible to your unaided eyes. Another feature of binocular glasses is that they are detachable, meaning you can disassemble them into small parts, convenient to carry. There are even some models which can be flipped upwards, breaking no squares to your reading.The greatest advantage they bear is the high quality optics. Wearing them, people will not experience eye strain or eye fatigue. What is more the patented grid system allows anyone be able to wear them according to their head sizes. They can also be customized according to the number that you have.
