Reading the size of your glasses involves looking at the inner arm or bridge where you'll find a series of numbers. Typically, these numbers indicate the lens width, bridge width, and arm length (in millimeters), in that order. For example, a marking of 50-20-145 means the lens is 50mm wide, the bridge is 20mm across, and the arm is 145mm long. Understanding these measurements is crucial for finding a pair of glasses that fits well and feels comfortable throughout the day.
