Product Information
Sunglasses
All our sunglasses are guaranteed to absorb more than 99% of harmful UVA and UVB rays. They meet ANZI Z80.3 high UV protection standards and have been proven and recommended in accordance with the latest guidelines. They reduce infrared rays and filter colour while maintaining high levels of visible contrast. They have passed the FDA requirements for impact resistant lenses. They are lightweight, comfortable, durable and reduce glare. As a result, they are almost unbreakable under normal use.

Many of our sunglasses have optically-decentered lenses

Polycarbonate Lenses: These are a higher quality material than standard acrylic lenses. They are particularly popular on one-piece and sports styles due to the ability of the material to bend without breaking and to be shatterproof.

Polarised Lenses: Polarised lenses have the benefit of filtering out reflected light and glare off water, pavement and snow. This lens works great for fishing, boating, driving or any other glare intensive activity. Polarised lenses are the best way to eliminate both glare and UV light. Polarisation is achieved by magentically aligning the plastic/polycarbonate fibres in the lens to reduce refraction as light passes through the lens.

Flash Mirror Lens Coating: A special treatment is applied over the base tints to reduce light and glare. Flash mirror gives a slight mirror finish to the lens.

Ski and Snowboarding Goggles

Looking After Your Eyes
Be safe as well as stylish: you should never ski without sunglasses or goggles, even on overcast days. Excessive exposure to ultraviolet light can cause snow blindness, which may result in permanent damage to your eyes. When you buy sunglasses for the slopes, make sure they are polarised and preferably wrap-around. Never ever ski with glass lenses, always polycarbonate. Ski goggles are preferable when visibility is poor and for powder or serious bumps skiing. If you wear prescription glasses, look for ski goggles and ski sunglasses that accommodate them.

Looking After Your Ski Goggles

How should I clean my lenses?
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 may 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.    

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.
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.
Revo Mirrored: Revo Mirrored lenses are a multi-layered titanium which provides a brilliant rainbow color. Discovered by aerospace engineers at NASA, these high-tech lenses have 12 layers of titanium dioxide and silica applied onto shatterproof polycarbonate. They are also scratch resistant.
Amber Mirrored: Amber lens with partial mirror coating. Amber lenses enhance contrast, enabling you to make out shapes, objects, and bumps in the snow more clearly because it blocks out the blue, or hazy, end of the color spectrum.
Rose Mirrored: Rose lens with partial mirror coating. Rose lenses enhance contrast, enabling you to make out shapes, objects, and  bumps in the snow more clearly because it blocks out the blue, or hazy, end of the color spectrum.
Polarized Smoke: 1.1mm Polarized smoke lenses. Eliminates glare and enhances constrast which improves visual acuity.
Brown Lens: Enhance the light quality of your surroundings while giving the wearer added depth perception in lower light conditions.
G15 Lens: Greenish/gray lens, remains a popular choice. Many believe this tint offers better contrast than gray, yet is more neutral than brown. G15 lens has a transmission rate of 15%.

What can I do about my eyewear fogging up?

We have a few hints:
Do not overdress. Be warm, but not too warm. 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 ski 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.-.it 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. You can 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 although our eyewear has dual anti-fog coating, there is always a possibility that goggles will still fog-up under extreme conditions. **
