Opera Glasses ” Fashion Wear, Spyware Or Optical Instrument?

Opera glasses developed from a series of other inventions. All this started in 1608 when the Dutch optician Hans Lipperhey created binoculars consisting of two parallel telescopes. Their magnification capability was a (very impressive for the time) x3. Within one year the Italian mathematician and philosopher Galileo Galilee made massive improvements to the techniques and types of lenses used in telescopes, thereby increasing the magnification ability to 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.

The next step forward was made when an Italian gunnery officer by the name of Ignazio Porro developed prismatic binoculars during the ’50s. These offered an even wider field of vision than earlier binoculars and also a drastically improved magnification ability.

The first time we find opera glasses mentioned in the printed media is in London during 1730. The opera glasses advertised were in fact not binoculars, but rather pocket-sized Galilean telescopes. They were used as much for decorative purposes as to watch the opera. The bodies were frequently decorated with mother of pearl, enamel, ivory or various types of gems.

Binocular-type opera glasses made their appearance for the first time during the ’20s in Vienna. These early types were basically still only two small telescopes with a connecting bridge. The individual telescopes had to be focused by pulling out 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!
