    if i remember correctly, the Arabs invented it.

    Although the dates vary by 2 years, below you will find 2 possible answers…

    A binocular is a optical instrument for providing a magnified view of distant objects, consisting of two similar telescopes, one for each eye, mounted on a single frame. The first binocular telescope was invented by J. P. Lemiere in 1825.

    Binoculars – In 1823, a new optical instrument began to appear in French opera houses that allowed patrons in the distant (and less expensive) seats to view the opera as if they were in the front row. Called opera glasses, the device combined telescope lenses with stereoscopic prisms to provide a magnified, three-dimensional view. After many years (but relatively few modifications), opera glasses have evolved into the binocular.

    In their simplest form, binoculars are a pair of small refracting telescope lenses, one for each eye. The brain assembles the two views, one from each lens, into a single picture. Because each eye sees its own view, the final image has depth; this is not so with conventional telescopes, which possess only one eyepiece and, therefore, a two-dimensional image.

    Phoenicians cooking on sand discovered glass around 3500 BCE, but it took about 5,000 years more for glass to be shaped into a lens for the first telescope.

    A spectacle maker probably assembled the first telescope. Hans Lippershey (c1570-c1619) of Holland is often credited with the invention, but he almost certainly was not the first to make one. Lippershey was, however, the first to make the new device widely known.

    “What we call a binocular is a binocular telescope, two small prismatic telescopes joined together. When Hans Lippershey applied for a patent on his instrument in 1608, the bureaucracy in charge, who had never before seen a telescope, asked him to build a binocular version of it, with quartz optics, which he is reported to have completed in December 1608.”

    That was an interesting question, so I had to look. The first telescopes came in around 1600 and it seems the first thing people wanted to know was if there was a way to see through with both eyes. That doesn’t qualify as a new concept because that’s how we use our eyes naturally. Binocular telescopes were alright if you wanted to look at the world upside down through a cumbersome contraption. Ignatio Porro patented a prism erecting system in 1854, but making it work required better glass, skills, and one more step. That step was made by Ernst Abbe, who glued the prisms together by 1873 to make an erecting telescope. Otto Schott was a glassmaker and Carl Zeiss was an instrument maker, so everything came together in Germany and was first sold in 1894.

    World war one broke out soon afterward, and that didn’t hurt the popularity of these new instruments.
