Polycarbonate Lenses
Shatterproof Polycarbonate lenses are optically correct for zero distortion to provide outstanding optical performance and enhanced vision in any lighting condition. Polycarbonate is the newest development in lens materials. It is a type of LEXAN® from G.E., the same material used for bullet resistant glass in autos. It is such hard material that a special diamond grinding wheel must be used to cut the lens. To form the glasses the material is melted and then force injected into a special mold. The Polycarbonate material is naturally UV absorbing, so even the clear lenses are 100% Ultraviolet protected. Polycarbonate in certain glasses is actually approved for use as safety glasses. Polycarbonate lenses are lightweight, durable, impact-resistant and the most scratch-resistant of the plastics. They are virtually break proof. Polycarbonate eyewear is the only approved eye protection for most major Police & Fire Departments.

Lens Tints and Coatings
Smoked & Gray
The most common type of lens color. Ideal for bright light conditions without changing color perception, making them a good choice for all-weather use.

Amber & Brown
Especially good at blocking the blue light commonly found in diffused light such as one might experience on a cloudy day. Amber can improve both contrast and depth perception, and is a good all-around choice if you live in an area with changeable weather patterns.

Yellow
Improves contrast and gives a sensation of heightened visual acuity. Ideal for overcast days.

Clear
Untinted for low-light or nighttime eye protection.

Clear Mirrored
A clear lens with a flash mirror coating that provides a one-way mirror. Good for bright and low light conditions.

G-Tech
These high tech lenses have from 7 to 13 layers of titanium dioxide and silica applied onto shatterproof Polycarbonate Cleaning them is easy and they are scratch resistant. They also provide total UV protection and enhanced contrast with minimal glare.

Anti Fog Coating
Anti-fog coatings provide extra resistance against fog buildup and blurred vision.

Polarized Lenses
Light reflected from surfaces like a flat road or smooth water is generally horizontally polarized. The horizontally polarized light is blocked by the vertically oriented polarizers in the lenses, resulting in a reduction in annoying and sometimes dangerous glare. While ordinary tinted lenses reduce brightness, only polarized lenses eliminate glare. Polarization is achieved by sandwiching a thin sheet of polarized film between two layers of material. Polarized lenses work well for boaters, fisherman, skiers, golfers, bikers and joggers who require a clearer view and the elimination of glare.

Photochromic Lenses
These lenses are designed to automatically adjust to the amount of ultraviolet light (UV) that reaches the lens. The transmission rate is the amount of visible light penetrating the lens and reaching the eyes. The higher the transmission rate the lighter the lens color. Clear lenses have a transmission rate between 80-100% and typical smoke lenses have a transmission rate between 8-18%. Photochromic lenses do NOT get as dark as traditional smoke grey lenses. The advantage of Photochromic lenses is that you can wear your eyewear from morning into evening and not have to have multiple sets of eyewear with you or have to change your lenses throughout the day.

Interchangeable Lens System
Interchangeable lenses provide options for all lighting conditions. In most cases you use the same frame and interchange the various lenses to meet your varied light conditions. Darker lenses for bright light conditions, Yellow or Amber lenses for dawn/dusk or overcast conditions and Clear lenses for nighttime.

UV Protection
All of our eyewear provides the industry standard UV 400 eye protection and is warranted by the manufacturer to meet or exceed applicable US Government standards for ultraviolet protection.

Foam Padding
Many styles of the eyewear you will find on our website come with foam padding. The foam reduces wind flow, prevents debris from getting into your eyes and reduces vibration. There are three types of foam padding: open cell, closed cell and neoprene.

Open Cell Foam tends to be lighter, softer and more sweat absorbent than closed cell foam. Open cell foam also can provide a better seal or fit because its softer and conforms to the contours of the face better.

Closed Cell Foam has low water absorption making it more weather and chemical resistant. It also provides some ventilation to reduce fogging and can be more durable than open cell foam.

Neoprene Foam is a flexible and durable sponge rubber that provides good thermal and moisture insulation and form fitting which is able to resist ozone, sunlight, oxidation, many petroleum derivative and chemicals.

Venting Systems
Venting Systems incorporate exhaust vents into lens and frame designs to enhance airflow and virtually eliminate fog and condensation. This design feature allows maximum ventilation while blocking extraneous incoming light.

Nose Grips
Nose grips create a non-slip grip that keeps sunglasses securely in place during athletic activity. This self-adjusting material ensures a soft feel and custom fit regardless of head shape or size.

Temples / Earstems
The temples on some models are curved to shadow the contours of your head without putting pressure on your temples. Some are then wrapped in a non-slip material to ensure they stay securely and comfortably on your head. This advanced anatomical design ensures a secure fit with exceptional comfort.

Hints
If you're in and out of the sun constantly, like a delivery driver, a cord is a must, or you’ll have to be putting your sunglasses away all the time.

Don't leave sunglasses with plastic frames on the dashboard of your car on a hot day. You don't want your sunglasses to "melt" and lose their form.

Storage
It's always best to place your sunglasses in a case when you aren't wearing them. Not only will it help in preventing them from becoming scratched, but it will also protect them from accidentally breaking, like someone sitting on them.

Avoid placing your glasses without a case in your purse or pocket. Keys or combs can easily scratch them.

Cleaning
Clean dust and lint from your lenses with a soft cloth. The best cloth to use is a Micro Fiber cloth. Using a Micro Fiber Cloth will ensure that the lenses do not become scratched.
