The History of Opera Glasses

For about 100 years, opera glasses only existed as telescopes. In Vienna in 1823, the first binocular opera glasses and theater binoculars were made. They were two simple Galilean telescopes with a bridge in the center, each telescope focused independently of the other by extending or shortening the telescope until a desired focus was achieved, which was useful, but also very heavy.

The first binoculars made of two parallel telescopes were built in 1608 by the Dutch optician Hans Lipperhey. They had the capacity to grow up to three times. A year later, Galileo Galilei (1564-1642), an Italian philosopher and mathematician, enlarged the telescope by about 30 times. Johann Kepler (1571-1630) invented the telescope, which gave a very wide field of view. However, because they had two convex lenses, the image that was seen was inverted.

Around 1617 Anton Schyrle (1597-1660) added an additional lens and the image was renamed the terrestrial telescope. In 1758 John Dollond of England solved the main problem that all binoculars had at that time – chromatic aberration. He invented a lens made of two lenses cemented together. Each lens was made from a different type of glass. This is the achromatic (colorless) lens that is still in use today.

In the middle of the 18th century, a Venetian optician named D. Salva (1710-1762) invented a bridge connecting two small Galilean telescopes. This bridge is still used today.

In the middle of the 19th century, a very important development took place. An Italian artillery officer- Ignazio Porro (1801-1875) found a way to use Keplerian telescopes and rotate the image using prisms. This change ushered in a new generation of prismatic telescopes with a wider field of view and higher magnification capabilities, rendering the Galilean telescopes almost obsolete.

There are two main types of Opera glasses: Monocular and binocular. There are 4 subgroups of binoculars: Lorgnette: binoculars with an extended handle, miniature (3-4 cm in length), unusual: such as Jealousy Glases, which had a mirror on the side to allow close observation of other people and regularly. Most of the production of Opera bottles was done in continental Europe: France, Austria and Russia.

Today, in modern opera glasses, the design Galileo implemented in his first telescope 400 years ago is still used today, although there have been many improvements in design over the years. Opera glasses offer a front row view, no matter where you sit. Opera glasses and theater binoculars are now available in many varieties. There are opera glasses with chains, handles and lights to read your program during the performance. They are also available in many materials, styles and colors to suit every personality.

The group of technological innovations and analyzes in optics may have later influenced two opticians, Johann Friedrich Voigtlander, an optician in Vienna, and the English optician JT Hudson in the 1800s to create the only thing that came to be known as opera glasses or theater remotes are recognized.

Aristocrats in Europe in the 1900s placed large amounts for opera glasses as they denoted fashion in addition to taste and wealth. Currently, because opera is certainly still very much in vogue, a similar tool performs the same function. Since the type is most likely not as old as the 1900s, a set of opera glasses is mostly desired because of its actual functionality.
