Opera glasses was one of the byproducts of a long line of inventions. It started during 1608 with the Dutch optician Hans Lipperhey manufacturing binoculars comprising of two twin telescopes connected by a centerpiece. They had an impressive magnification ability of x3. Not to be left behind the Italian inventor Galileo Galilee within a year dramatically improved the design of telescopes, allowing a magnification of x30.

Initially binoculars had one major drawback: Although they allowed for a much wider field of view, they used two convex lenses, which inverted the image! It took more than 100 years for the next major step forward: in 1617 Anton Schyrle constructed binoculars with an additional lens that re-inverted the image. More than–0 years later a certain John Dollond of England started manufacturing achromatic (color-free) lenses and with that solve another problem bugging binoculars – that of color distortion.

Another major step forward was the development of prismatic binoculars by an Italian by the name of Ignazio Porro – a gunnery officer. Prismatic binoculars had a much wider field of vision than before and offered dramatically improved magnification abilities as well.

Opera glasses are mentioned for the first time in London newspaper advertisements dating back to 1730. These were not binoculars, but small Galilean telescopes. They were both used decoratively and to watch opera with. The bodies were often inlaid with gems, mother of pearl, ivory, enamel and other types of decorations.

We find references to binocular opera glasses for the first time in Vienna during 23. They were still really not much more than two tiny telescopes connected by a bridge. You had to focus the telescopes individually by expanding the tubes.

These very soon became as much a fashion item as an optical instrument. The designs became more elaborate and had to be worked on by painters, goldsmiths and other artists to create the ultimate fashion accessory. Theater goers not only used this to watch the stage, but also to scrutinize other people in the audience – presumably to see who else had opera glasses!

The design soon improved to allow for the simultaneous adjustment of both lenses. This was another major step forward and only served to increase the popularity of this type of glasses. They also became highly valued gifts – as one can see from the inscriptions found on many opera glasses of the time.

Nowadays there is a wide array of opera glasses available. You can get them in virtually any color you want. They come in many different styles and materials. Strangely enough, monoculars are still popular, as are opera glasses with handles or reading lights. You even get them fitted with a jealousy glass – so you can watch another person in the audience without being seen!

Jeff B. has always loved the theater and opera, he currently helps run an opera glasses retail site where they sell opera glasses. Including Opera Glasses with handle, flashlight, chain and more!
