Global Fit sunglasses are designed with alternative proportions to better accommodate features such as wider heads, lower nose bridges and higher cheekbones. They offer another fit option for people who find standard sunglasses uncomfortable or difficult to wear.

Global Fit frames may feature adjustments to the frame width, bridge design, lens position and temple arms to provide a more comfortable fit for different facial proportions. The exact design details can vary between styles.

You may find Global Fit sunglasses more comfortable if standard frames feel too narrow, slide down your nose or rest against your cheeks. They may also be worth considering if your eyelashes touch the lenses or the temples feel tight around your head.

The terms are often used to describe similar alternative-fit designs, particularly for people with lower nose bridges. However, Global Fit can refer to a broader range of proportional adjustments, including frame width and temple design.

Check the frame measurements, usually printed on the inside of the temple arm, including lens width, bridge width and temple length. Comparing these with a pair you already find comfortable can help you choose a suitable size. You can also consider how the frames sit across your nose, cheeks and temples when trying them on.
