Made in Japan.

The Mami Vantage Ti is a rounded, dual-lens, six-base rimless sunglass system built with ultra-lightweight, durable betatitanium temples.

Custom anodized titanium hardware pairs with hypoallergenic rubber nose pads and temple tips.

The frame is equipped with D+ therapeutic-grade lenses, manufactured from shatterproof polycarbonate for enhanced durability and impact resistance. The lens surface is treated with anti-reflective and oleophobic coatings to minimize glare and repel water and oil, ensuring complete protection and optimal visual clarity.

Our D+ Photochromic lenses are rated CAT0-3 and transition from clear to grey in response to UV exposure. In direct sunlight, they reach approximately 20% visible light transmittance within 30 seconds and 15% within 60 seconds. Because the lenses are activated by UV light, they will not darken behind most car windshields or windows, which filter the majority of UV radiation.
