Sunglasses and Eyeglasses Size Guide
Choosing the correct eyewear size can be a frustrating and uncertain experience, as identifying the perfect frame goes beyond simple style selection. Factors such as face shape, bridge size for a comfortable nasal fit and temple length for optimal stability are crucial elements for finding the right fit.
Fortunately, you don't have to navigate these complexities alone. Our comprehensive eyewear dimensions guide breaks down key frame measurements, empowering you to confidently select the dimensions that best suit your needs.
How to read glasses size?
You have likely noticed a series of small numbers engraved on the inside of the temple arm and wondered what they mean. These figures are the key to how to read glasses size correctly; they indicate the precise frame dimensions.
The first two numbers indicate the lens width (also known as caliber) and the bridge width. The third number indicates the temple length. These values are always displayed in this specific order and measured in millimeters (mm) for international accuracy.
Lens Width (Caliber): This is the horizontal width of just one lens at its widest point. It’s the most important number for determining the overall fit and style of your frames.
Bridge Width: This is the distance between the two lenses. It represents the part that rests on your nose, ensuring your glasses stay comfortably in place without slipping.
Temple Length: This is the total length of the arms of the glasses, measured from the hinge to the very tip that curves behind your ear for a secure fit.
