Maui Jim Byron Bay sunglasses in marlin are as pristine as the coastal beach town they're named after. These shades offer optimum comfort and style with their fitted Maui Jim bi-gradient mirror lenses. Your eyes will be treated to ultimate comfort and optimized clarity with this squint technology, where the mirror is applied to the top and bottom of the lens to block out harmful rays, while the darker area in the middle of the lens squints for you. Maui Jim’s mission is to uncover the importance of high quality eyewear. All Maui Jim sunglasses feature the signature PolarisedPlus technology which blocks out reflected glare from every angle. This helps the sun seekers stop the glare and harmful UV rays on a daily basis.
