what size sunglasses do i need

To find the right size of sunglasses, you can measure your face in a few different ways. One method is to hold a ruler horizontally across your face and measure the distance between your temples. You can also use a pair of sunglasses you currently own to determine your best size. Frame sizing is typically noted on the inside of either temple. The eye size is usually first, then the bridge size, then temple size. Use the eye size to determine the best frame size. Most sunglasses have three numbers printed on the inside of the temple arm, which are the frame dimensions expressed in millimeters. These numbers refer to the lens width, bridge width, and temple length. Adult sunglasses lens widths typically range between 49mm and 63mm, with the bridge width typically being between 16mm to 24mm, and temple length ranging from 135mm to 150mm. There is no one “average” size for frames as everyone’s face shape and size is unique. Its important to choose the correct size to ensure that your sunglasses sit comfortably and securely on your nose without sliding up or down, and to enhance style and overall appearance.
