Glasses are an essential accessory for people who suffer from visual impairments. However, glasses can be referred to by a variety of other names, including spectacles, eyeglasses, or simply frames. Spectacles are typically used in formal contexts, while eyeglasses tend to be more colloquial. Some people might also refer to their glasses as specs or peepers. Other variations of glasses terminology include bifocals, which are glasses with two lenses for different distances, and progressives, which are multi-focal lenses with a gradient of power. No matter what you call them, glasses remain a crucial aid for vision correction, preventing eye strain, and helping individuals with visual impairments lead their best lives.
