Definition
Noun: * Opera glasses: A small, handheld optical instrument, typically a pair of low-magnification binoculars, designed for use in theaters, opera houses, or other venues to view distant stage performances more closely. They are characterized by being compact, often elegant, and intended for simultaneous use by both eyes.
Usage
