Opera Glasses are similar to binoculars but they are made for being able to see performances on stage. In old opera houses seats placed in balconies that were subsequently cheaper were very far away from the stage. In some they were so far away on the figures could be seen from that distance but seeing facial features, and thus part of the acting, was impossible to make out. Opera glasses would enable those people in the peanut gallery to see on stage much better to the point of seeing the facial expressions of the actors or singers. They have been popular since the 50's.

Opera glasses are different from binoculars as they are made to be smaller and some where made not so much to look utilitarian but to look stylish. Some pop up from a flat looking case and are easily carried in women's clutch bags or in suit coat pockets. Others fold so that they can easily be carried around without notice. There are some that mimic those of the past with a single rod attached called a lorgnette, so the glasses can be held to the eyes with only one hand. This folds up as well.

Opera glasses are easily purchased even in today's market. A cheap model may cost under $100 US dollars, at around $50, but they can go up in price to hundreds of dollars. The expensive types will have better optics and magnifications and probably be a little more fashionable as well. Vintage opera glasses can cost increasingly more dollars just because of the fact they are old. Just make sure they still work well.

Many opera houses and theaters have opera glasses for rent and the price for renting is generally inexpensive. If you frequent the opera or the theater often it may be better to own a pair, but if you only go every so often renting may be the thing for you. It is also suggested if thinking about purchasing a pair to rent different types to see which will be more favorable to your liking. Some people like the ones better that are on the long rod and employ the use of only one hand better, while others don't mind using both hands. Some people find they don't even like using them at all.

Opera glasses are different in another way from binoculars. The optical system used is much simpler than that used in binoculars. It is known as the Galilean optical system and based on the system that was invented by Galileo. The view is not as sharp with opera glasses as it is with binoculars but it still enables you to see what is happening on the stage.

Most opera glasses today are made in China. Most of them have a magnification to 3 X which is adequate for a large auditorium or concert hall. Exceptions to the rule go to 5 X but they are quite expensive. Some will have a center focus and some don't have one at all. Usually the non focus glasses have a small red LED light that appears between the eye barrels. This will enable you to read the program in dim light without disturbing your neighbor. If you have good vision these will be the ones for you however, if you have a problem with vision and wish to use the opera glasses without your corrective lenses it is better to go with the ones that can be focused. Since there is a central focusing mechanism there is no room for the light so focused opera glasses will not have one.

Opera Glasses usually are accompanied by a case and especially look for this in the vintage ones. Some are soft sided and others hare hard and can be lined with velvet. Some antique glasses are made of ivory or enamel with cloisonne and they may be bejewelled or framed in gold or silver. Old ones were very beautiful and elegant. Either vintage or modern glasses make a great gift for those who love the ballet, opera or theater.
