WIND DOWN™ LENSES

Proprietary lens developed with Dr. Andrew Huberman to filter out most of the visible blue and green light spectrum. Every lens comes with premium anti-reflective, anti-scratch, and hydrophobic coatings for comfort and durability.

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.

SPRING HINGES

Rated to 25,000 cycles. Our precision hinge engineering means no loosening over time. Functionally they act like suspension while exercising and make for a more comfortable fit.

INTERCHANGEABLE NOSEPADS

Every pair comes with multiple sizes of GEKO™ nosepads, so you can tune your fit and eliminate uncomfortable pressure points.

Wind Down™ Lenses

You'll be seeing red, and that's the point. This lens technology is scientifically designed to filter blue and green light (short wavelength light) in the evening, while letting through beneficial red light. The results, better sleep and less stress.

THE SCIENCE

Exposure to blue and green light (short wavelength light) at the wrong time of day can hinder your ability to wind down for sleep and disrupt your circadian rhythm. In modern society, artificial light from cell phones, computers, overhead lights, and other sources are prime offenders. Even minimal artificial light exposure can interfere with your natural rhythm and suppress melatonin production, a crucial hormone for sleep regulation. Our Wind Down™ lenses have been designed to filter out the light in the 400-520nm range of the visible light spectrum. When worn at night, these lenses help prevent disruption and support keeping your brain and body in sync with your circadian rhythm.
