Opera Glasses came into existence as a result of a long line of inventions, and further improvements upon those inventions. The process started in the year 1608 when a Dutch optician by the name of Hans Lipperhey developed the first pair of binoculars with a magnification capability of X3. Less than a year later, a well-known inventor and philosopher by the name of Galileo developed what became known as the Galilean telescope. Advertisements were first found for opera glasses and theatre binoculars in London as early as 1730 in the form of a long collapsible telescope. The "Opera Glass" as it was referred to; was often covered in enamel, gems, ivory, or other art and paintings. For almost 100 years opera glasses existed merely as telescopes. In Vienna, in 1823 the first binocular opera glasses and theatre binoculars began to appear. They were two simple Galilean telescopes with a bridge in the centre, each telescope focused independently from the other by extending or shortening the telescope until the desired focus was achieved, which was useful, yet very cumbersome. Two years later in Paris, Pierre Lemiere improved on this design and created a centre focus wheel. This allowed the focusing of both telescopes together. After this development, opera glasses and theatre binoculars grew in popularity because of the superior view they facilitated in opera and theatre houses. The beautiful design of the glasses themselves also added appeal to the opera-going crowd. By the 1850's opera glasses and theatre, glasses had become a must-have fashion accessory for all opera and theatergoers.Not very significant as not associated with a historic event or person and made during the first half of the 20th Century and many are still available and easily sourced.Vintage Pair of Opera Glasses, with cow bone barrels and eyepieces, both barrel pieces have split in them, both metal end barrels each have a minor dent, optics are pretty clear no mould although have very minor dust spots inside, they look like they were gilded at some point but most of this has rubbed off glasses have a black leather case with blue lining.
