What measurement is important for fitting glasses properly?

The bridge width and temple length are critical measurements for ensuring that glasses fit properly. The bridge width determines how well the frame will sit on the nose, affecting both comfort and the position of the lenses in relation to the eyes. If the bridge width is too narrow or too wide, it can lead to discomfort and misalignment, which can impair vision.

Temple length is equally important because it influences how the frames sit on the ears and how securely they stay in place. An appropriate temple length ensures that the glasses do not slide down the nose or pinch the sides of the head. Together, these measurements are essential for achieving a comfortable fit that maintains proper optical alignment, enhancing the wearer's overall visual experience.
