Unless you are seated in a huge auditorium or concert hall 3x is adequate. Opera glasses have a standard measurement of 3x20 - 3x magnification with a 20mm objective (front) lens.

Your choice in terms of magnification is limited to 3x. The good news is that nearly any opera glass on the market will be priced under $100. To be sure, there would be no point in investing high grade, expensive lenses in an optical system that cannot use them efficiently. After all, this is not a system that is intended to produce razor sharp optics, no matter how well ground the lenses are. Today, nearly all opera binoculars are made in China and, in terms of optics, there is really no one brand or model that is significantly sharper than the rest.

Still, an opera glass can provide quite useful, pleasant views of the performers and the stage. If razor sharp optics is your goal, you are better served with a conventional, low-power binocular. The disadvantage of such a system is its lack of optical clarity and correction. This keeps the price down and also allows for a very compact design. The advantage of this type of optical system is both its simplicity and its very short optical length. This system is officially known as a Galilean optical system, since it is a very simple system similar to what Galileo used in his optical designs. Internally, opera glasses use a simpler optical system than conventional binoculars.
