Why we made Zilker Prescription Sunglasses.
The smaller sibling of our Halsey glasses, this timeless silhouette is great for smaller faces. It's packed with tech and features to make it fit, feel, and perform like a cutting-edge frame, but we crafted it to look like something a bit more casual. Take them anywhere you want to go, they won't let you down.
CORE TECHNOLOGY
FLOATFIT™ FRAMES
We obsess over every detail across design, engineering, and materials science to ensure your frames can keep up with anything you throw at them. The result is a frame that is extremely durable, lightweight, comfortable, and will stay on your face. We call this Float Fit, and we invite you to feel the difference.
NO-SLIP GEKO™ PADS
Proprietary formulation enhances fit and retention, relieves pressure points, and gets stickier when wet.
PREMIUM LENS TECHNOLOGY
Color. Contrast. Clarity. Our proprietary lens designs offer best-in-class optics with UV protection + anti-scratch, anti-reflectance, and hydrophobic coatings as standard issue.
NO PRESSURE POINTS
Every pair comes with multiple sizes of GEKO™ nosepads, so you can tune your fit and eliminate uncomfortable pressure points.
"The lens quality is impressive, providing excellent protection against harmful UV rays, a comfortable fit, these shades are perfect for any occasion.
