Try Purchase Opera Glasses To See The Performance

By Jeff Bridges

Opera glasses, also called theater binoculars are compact low powered optical devices that are used to bring the show closer to theater patrons. Originally they were for use at the opera. Magnification of opera glasses is limited due to the low light conditions of most theaters to about a 3x power.

Opera glasses compare in some ways to binoculars. However, opera glasses are designed for indoor use. They are found useful at indoor theaters and in many other performances where seats may be located some distance from the stage, as in balconies or the back of the theater. The glasses give the patron the ability to see the stage from the far away locations.

Opera glasses work on a different optical basis than do binoculars. Binoculars are classified as a matched set of folded telescopes while opera glasses are made on the principle of a Galileo's first telescope. They have a convex lens nearest the stage and a convex lens nearer the eye. This makes the image to appear right side up, unlike other telescopes. The image is not the quality of binoculars, but is still acceptable for indoor viewing of shows. In addition mirrors are not needed as they are in binoculars.

Opera glasses are designed to be very small. They are not meant to be obtrusive or distracting to any other of the theater goers. Some of the models are made to fold in order to fit into a pocket or a purse.

Use of opera glasses may take some work to get used to. One way to see if you enjoy the use of opera glasses is to rent a pair. Rental is often available in larger theaters where they are needed most and inexpensive.

During the nineteenth century, opera goers used spectacles that had a long handle called a lorgnette. These glasses were more ornamental than useful. The lorgnette was preferred to spectacles by some of the more fashionable ladies. Some of the fancier opera glasses that are used today are shaped after the lorgnette of that time.

The use of opera glasses is truly a personal choice. They may be helpful in following the story line for some patrons however others find them to be annoying and unnecessary to follow the story line. The other factor may be the seat that you choose. While better seating may be more expensive, it often offers a much better view of the show without requiring the use of opera glasses. - 18423
