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.
One of the final important developments in binocular technology happened when the Italian gunnery officer Ignazio Porro invented prismatic binoculars, thereby once again increasing the field of vision dramatically and making much larger magnification possible.
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.
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.
They proved to be very popular, however, and quickly became items of high fashion. The designs were so elaborate that one often would find both a painter and a goldsmith working on the end product. They were used as much to impress people as to watch opera - not to mention scrutinizing other opera goers to see if their opera glasses were perhaps more fashionable than yours!
Within a few years the design was improved to make it possible to simultaneously adjust both lenses. This led to an immediate increase in the popularity of this type of glasses. They also turned into much appreciated gifts - as is apparent when looking at the inscriptions encountered on many opera glasses dating from that period.
The variety of opera glasses available at present is very large. You still get monoculars, which are considered to be very stylish. You also get glasses with built-in reading lights and others with handles. You can even get one with a built-in jealousy glass - enabling you to discreetly watch someone in the audience without being noticed.!
