What Those Numbers on Your Glasses Mean (And Why You Should Check Them)

The numbers on eyeglasses that pertain to the size of various parts of the glasses are usually associated with the frame dimensions. These measurements are essential to ensure that the eyeglasses fit comfortably and provide the best vision correction. Here are the main measurements and what they indicate:

1. Frame Width (Lens Width): This is the width of each lens measured from the widest points. It helps determine the width of the frames and how they will fit your face.

2. Bridge Width: The bridge width is the distance between the inner edges of the lenses, where the nose pads sit. It's important for determining how the glasses will rest on your nose.

3. Temple Length: This is the length of the temple (the arm that goes over your ear), typically measured from the hinge to the end of the temple tip. It's important for ensuring the glasses fit comfortably around your ears.

4. Lens Height (or B Measurement): The lens height is the vertical measurement of the lens, typically measured at the tallest point of the lens. It helps determine how much vertical coverage the glasses provide.

5. Frame Width (Total Width): This is the total width of the frame from one end to the other, including both lenses and the bridge.

These measurements are crucial for selecting frames that fit well and are proportionate to your face. Frames that are too wide, narrow, short, or long may not provide adequate support, comfort, or proper vision correction.

When choosing new eyeglasses, an optician or eyewear professional will often guide you in selecting frames that match your facial features and prescription requirements based on these measurements. Additionally, online eyeglass retailers often provide these measurements on their websites to help customers choose frames that will fit well.
