With this in mind, Costa recently introduced its new Omni Fit line of premium sport performance sunglasses designed to fit faces of every ethnicity. The brand customized seven of its most popular styles to feature a modified Distance Between Lenses (DBL), flatter head curve and deeper adjustable nose pads. The Omni Fit collection adapts to fit faces with higher cheekbones, longer eyelashes and flatter nose and cheek facial structures, providing a more comfortable and secure fit.
