If it wasn't for the Dutch optician Hans Lipperhey, we might not have had either binoculars or opera glasses today. He first started manufacturing simple binoculars in 1608. These were not much more than two telescopes connected by a central bridge, but they led to many further modifications and improvements. His early binoculars had a magnification capability of x3. Within less than a year the Italian mathematician and inventor Galileo Galilee made another drastic stride forward by increasing the magnification ability of telescopes 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.
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.
We don't find any mention of opera glasses in the printed media before the 1730 - in London. These rather primitive opera glasses were not binoculars - they were mini-sized Galilean telescopes. People used them for decorative purposes as much as to watch opera. The bodies were mostly highly decorated with numerous gems, enamel, mother of pearl and ivory.
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.
They soon became highly fashionable. Going to the opera without one of these was social suicide. The designs became increasingly elaborate. Often you would find an optician, a painter and a goldsmith working on the glasses before they were finally ready for their discerning owners. Once at the opera, they were not only used to watch the stage though - they were also regularly used to check out the other guests to make sure there wasn't by any chance someone with a more elaborate set of opera glasses!
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.!
