Below is a list of Frequently Asked Questions. If the answers below do not answer your question specifically, please feel free to email us.

All of our 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.

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:

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.

We have a few hints:

Do not overdress. Be warm, but not too warm. Exercise, skiing, or any movement generates heat and if sweat is forming on your forehead, your goggles fog up. Take off a few layers until you are comfortable.

Snow. If it is snowing and your goggles begin to fog, check to see if the snow has clogged the vents. If they are covered, the heat cannot escape so do your best to remove the snow.

If your goggles do fog, never wipe them clean. Doing this reduces its effectiveness. Anti-fog treated lenses will heal themselves given time.

Never clean your goggles with glass cleaner...that removes the anti-fog coating and only use anti-fog sprays or liquids on your goggles when the factory anti-fog coating has worn off or been removed.

For eyeglass wearers, try putting on the goggles before leaving the indoors since this will prevent the glasses from getting cold. If snow/water gets on your glasses/goggles, blot the water droplets dry with a soft cloth. Even remove them and set them foam side down on your leg so the moisture-laden air can dissipate and the no-fog coating absorb the remaining moisture.

**Please note that most of our eyewear already has the anti-fog coating, see the descriptions to be sure. However, there is always a possibility that these goggles will still fog-up depending on the situations as said above. Extreme conditions can also affect the anti-fog.
