Why we made Alto Fusion Prescription Sunglasses

Weighing in at just 15 grams, Alto Fusion is where elevated design collides with everyday performance. This ultralight titanium frame is paired with an acetate ring for a modern, twist—our sleekest metal silhouette where style meets substance. Think featherweight comfort, premium materials, and a fit that moves with you, not against you.


The sculpted temples are fully adjustable for a custom fit and lined with our GEKO™ grip for that locked-in feel, no matter how hard you go. Even the silicone nose pads are upgraded with GEKO™, hugging your face with a soft, grippy hold that stays put without pressure. And with our C3 Optics™, you’ll get the pop of color, contrast, and clarity that makes everything look just a little better.


Alto Fusion is a limited-edition release that redefines minimalism. With bold style and our signature performance DNA, eyewear has never looked - or felt - this good.
