Definition
An eyeglass is a single lens used to aid vision, or one half of a pair of eyeglasses. 👓 It can be a simple magnifying glass or a corrective lens. Think of it as a basic tool for improving sight. Unlike contact lenses, it's external and doesn't go directly on the eye. It can be part of a pair of spectacles or used on its own. Imagine a detective using one to examine clues closely.🔍
