Polarized lenses fight glare by minimizing the passage of undesirable light to the eye. The result is sharper vision, more vivid color and greater depth perception.
Photochromatic lenses darken with UV exposure, adjusting to a variety of light conditions.
Anti-reflective lenses reduce distracting reflections that can bounce off the back of the lens into the eye.
Gradient lenses fade from a darker tint to a lighter tint, allowing for comfortable vision over a wide range of distance and lighting conditions.
Frames that have interchangeable lenses let you swap out lenses for different looks and performances.
Mirrored lenses have reflective coating that reduces the amount of light passing through to the eye.
To find your frame size, measure your features according to this guide:
Measured from outermost edges of lenses horizontally.
Approx. 40mil - 62mil
The distance between lenses.
Approx. 14mil - 24mil
Length of the temple piece - also known as the arm piece or earpiece.
Approx. 120mil - 150mil
All colors absorb light differently. Lens colors determine which parts of the light spectrum pass through the lens to your eye.
- Gray or "smoked" lenses protect eyes from dangerous ultraviolet radiation without distorting colors. They reduce glare and absorb the same quality of light at any wavelength, which makes them good for driving, prolonged wear and general use.
- Yellow lenses filter out near-UV blue light while allowing a larger percentage of other frequencies through. Since blue light creates glare, these lenses make everything really bright and sharp. Just don't use them for anything that requires accurate color perception. With yellow lenses, colors are very distorted.
- Brown lenses are good for general use. Like yellow lenses, they filter out a large proportion of blue light, but they offer greater clarity and contrast, and help you maintain optimal vision even in irregular light.
- Green lenses offer the highest contrast and greatest visual acuity of any tint. They also filter some blue light and reduce glare. This filter is recommended for prolonged use in extreme conditions.
- Purple and rose lenses offer the best contrast for object against a green or blue background, making them ideal for water sports.
