Some of our eyewear comes with interchangeable lenses. That means, they come with more than one set of lenses so you can interchange. Other Birdz products come with only the tint that is in the frame. Be sure to look at the eyewear description to find out what lenses are included. We have the following lens tints:

 

Smoked: Dark tint for daytime (bright and sunny days); decreases sunlight without distorting colors.

 

Clear: For low-light or nighttime, untinted for indoor or outdoor use.

 

Yellow: For overcast days, increases visibility and depth perception.
 
Amber: Enhance contrast, enabling you to make out objects/shapes more clearly because it blocks out the blue, or hazy, end of the color spectrum. Great for driving. 

 

Clear Mirrored: Clear lens with a partial mirror coating, used for both bright and low light.

 

Smoke Mirrored: Smoked lens with a partial mirror coating.

All of the goggle and sunglass lenses are Polycarbonate*. They are shatterproof, and are rated UV400 (100%UV protection). A special clear coating is applied to the lenses which blocks the ultraviolet (UV) rays. Obviously this is a transparent coating and can be applied to any color of lens including clear. *Our Polarized lenses are 1.1mm lenses that exceed FDA requirements for impact resistance.

 

Always rinse off your lenses with water before wiping or cleaning. Even tiny particles can be abrasive when rubbed across the lens surface. Clean your lenses by using an eyeglass spray or just warm water and a little dishwashing liquid. Never use a liquid cleaner that contains ammonia as this will harm the UV coating. Use a soft, clean cloth to wipe the lenses. Never lay your glasses face down or they can come in contact with something that may scratch the lenses. Storing your eyeglasses in their case when they're not in use always helps to keep them clean also.
