1. Opera glasses use different technology than many of today's binoculars. Based on Galileo's centuries-old design, concave eyepieces are paired with convex lenses. This is known as Galilean optics, which produces upright images with shortened lengths.
2. Compared to modern binoculars, opera glasses have significantly lower magnification power. The majority of
opera glasses offer 3x magnification, while higher-powered options should not exceed 5x. Greater magnification would limit the field of view and result in unstable images that might impede your enjoyment of the performance.
3. One aspect you'll want to consider as you shop for opera glasses is focus. Traditional designs are often fixed focus, which means you need only raise them to your eyes to enjoy an up-close view. Other models offer a center focus knob, which allows you to adjust the focus to accommodate different users.
4.
Lorgnette opera glasses are those distinctive models featuring a handle on one side. This is a convenient feature considering the compact size of opera glasses. Oftentimes, this handle can be adjusted in length and angle to ensure comfortable viewing.
5. Portability is key when it comes to opera glasses. And while all models are by nature compact,
folding opera glasses are arguably the most convenient to carry with you throughout the evening. These fit easily in a clutch or jacket pocket so you can access them when needed and easily stow them after the final curtain.
6. An attractive feature on many modern opera glasses is an
LED light, which allows you to view the playbill or program in a dark theater. This light is usually a soft red so your eyes (or those of your neighbors) won't be disturbed.
7. Beyond the opera house, opera glasses can be used to improve your vantage at concerts, plays, graduations, weddings, and other events and performances.
