What is the benefit of Serengeti's photochromic lenses and how do they differ from other brands?

All Serengeti sunglasses are photochromic and constantly adjust throughout the day to changing light conditions. This process is a seamless transition, which you may not notice while wearing them. It is best detected if you cover one half of one lens and take your Serengeti's outside in bright sunlight and wait 10 seconds and expose the covered half to show the darkening effect of Serengeti photochromic lenses.

Serengeti photochromic lenses are offered in both polarized and non-polarized options, while other brands may not offer photochromic lenses in non-polarized options. In addition, Serengeti's exclusive color hues are engineered to ensure high contrast and high-definition for an amazing view with superior clarity no matter the lighting condition.

Wearing Serengeti's results in less squinting and eye fatigue throughout the day while the lenses adjust darker to bright conditions and lighter to less-bright, overcast conditions. The Serengeti photochromic properties are embedded into each glass lens, so the technology last throughout the life of the lens.

What is Spectral Control?

Spectral Control® provides control over light and color. By managing colors within the visible light spectrum, this technology delivers stunning high-definition and color enhancement, while blocking out distracting blue light to calm and relax your eyes.

See a demonstration of the benefits of Spectral Control technology.

What is Blue Light?

Your eye will focus on blue images in front of the retina, which are difficult to distinguish, putting additional strain on your eyes. Blue light is also a major component of fog and haze. Serengeti lenses blocks distracting blue light, resulting in higher contrast of hazy images, as well as causing less eye strain and fatigue, which calms and relaxes your eyes.

What is the benefit of polarized lenses?

Polarized lenses work like venetian blinds, filtering light and eliminating distracting surface glare that can appear on the road and water, giving the wearer added clarity and comfort.

See a demonstration of the benefits of polarization technology.

What is light transmittance?

Light transmittance is the amount of light that passes through the lenses. Because all Serengeti lenses are photochromic and constantly adjust throughout the day, you'll notice we provide a range of light transmittance for each lens in its lightest and darkest state. Serengeti's unique lenses work all day to allow the perfect amount of light through the lens in every light condition for the ultimate in clarity.

What are the different frame materials Serengeti offers?

A lightweight material that's loaded with technology, taking the Genus collection where no sunglass has gone before.

Using only the highest quality injected nylon for superior durability, these fashionable frames have the added benefit of being exceptionally light, chemically resistant, extremely flexible and comfortable.

All natural and produced from cotton, Cellulose Acetate is not only lightweight, but it can be made into beautiful patterns and brilliant hues. Pliable when heated, it is ideal for custom fitting.

Lightweight, extremely strong and corrosion resistant, titanium is used in everything from sports equipment to space capsules. Beta titanium, a combination of vanadium and alumnium, is lightweight, strong and highly flexible, ideal for use in temples, as it expands the fit range of the sunglass. Memory titanium is a combination alloy that is flexible and lightweight, with the ability to return to its original shape when bent or twisted.

Titanium frames are 25% lighter than traditional alloys with unmatched durability. The technical benefits of titianium and the right, sophisticated aestetic of acetate make for a frame collection that is truly distinguished.

Made from corrosion-resistant and hypoallergenic titanium alloy, the frames are 25% lighter than standard alloy. So you're assured of not only a durable pair of glasses, but also a comfortable, secure and customized fit.

I just bought Serengeti sunglasses. How can I best take care of them?

On those rare occasions when you aren't wearing your Serengeti's, store them in their case. To clean lenses, blow loose particles off the lens and clean with an optical lens cloth or soft cotton cloth. A mild liquid soap diluted with warm water can also be used.

Do not clean your lenses with paper products, clothing or place lenses face down on any surface.

Do not leave your Serengeti's where conditions are intensely hot or cold and avoid putting your Serengeti's loose in a pocket or purse where lenses can be damaged.

What type of warranty does Serengeti offer?

Serengeti offers a two-year limited warranty against manufacturer defects. For additional information, click the 'more' button below for details.

How can I tell if my Serengeti lenses have an anti-reflective coating on them?

All Serengeti lenses feature an anti-reflective coating on the backside of the lens to block glare and distracting reflections resulting in increased clarity. The anti-reflective coating can be detected by the blue or purple coloration when looking at the back of the lens under a light.

What do I do if I feel there was a product defect that caused damage to my sunglasses? Will this be covered under warranty?

If you believe there may be a product defect, please return your glasses to our repair lab where we will be able to determine if there was a manufacturer's defect in the glasses, which caused this to happen. Though these situations are rare, if you purchased within the past year, and it is determined to be a manufacturer's defect, this should be covered under warranty.

See the instructions to return your product to our repair center.

How do I order replacement lenses or temples for my Serengeti's?

Why is there a Proposition 65 Warning on my Serengeti product?

A proposition 65 warning means one of two things: (1) the business has evaluated the exposure and has concluded that it exceeds the "no significant risk level"; or (2) the business has chosen to provide a warning simply based on the potential presence of a listed chemical. With Serengeti's products, the exposure may be below the Proposition 65 level of concern, or could even be zero. However, out of an abundance of caution, Serengeti has elected to place the Proposition 65 warnings on our products.

Proposition 65 mandates that the Governor of California maintain and publish a list of chemicals that are known to cause cancer, birth defects and/or other reproductive harm. The list, which must be updated annually, includes a wide variety of chemicals that can be found in dyes, solvents, drugs, food-additives, by-products of certain processes, pesticides and tobacco products.

A chemical can be listed if it has been classified as a carcinogen or as a reproductive toxicant by an organization deemed "authoritative" on the subject. For carcinogens, the U.S. Environmental Protection Agency, U.S. Food and Drug Administration, National Institute for Occupational Safety and Health, the National Toxicology Program, and the International Agency for Research on Cancer are deemed authoritative. With respect to reproductive toxicants, the authorities are the U.S. Environmental Protection Agency, U.S. Food and Drug Administration, National Institute for Occupational Safety and Health, and International Agency for Research on Cancer. A chemical can also be listed if it is required to be labeled or identified as a carcinogen or as a reproductive toxicant by an agency of the state or federal government.

A company with ten or more employees that operates within the State of California (or sells products in California) must comply with the requirements of Proposition 65. To comply, businesses are: (1) prohibited from knowingly discharging listed chemicals into sources of drinking water; and (2) required to provide a "clear and reasonable" warning before knowingly and intentionally exposing anyone to a listed chemical.
