| The Spy Sunglass Lens Technology | ARC®:
ARC® - "Accurate Radius Curvature" lenses are used throughout our high-wrap Spy sunglass collections to provide optically correct, distortion-free vision. Using the same technology astronauts and fighter pilots use on their helmet shields, Spy ARC® lenses complement the natural curvature of the human eye and become thinner as they move away from the optical center of the lenses. These lenses are engineered to eliminate distortion and provide a total absence of prismatic aberration and astigmatism. All Spy ARC® eyewear lenses are Optical Class 1 quality. |

CLASS 1 POLYCARBONATE (PC) LENSES:
Spy Optic's PC lenses are optically engineered to offer exceptional strength and shatter resistance. These lenses undergo extensive testing and will not crack or shatter when impacted by steel ball bearing at 160km/hr. Spy eyewear polycarbonate sunglass lenses have a polysiloxane coating that is heat-hardened at 120 degrees Celsius to give the lenses incredibly high resistance to scratching and abrasion.
CR-39 LENSES:
Many of Spy Optic's fashion frames are fitted with CR-39 lenses. CR-39 sunglass lenses offer unique and rich gradient color tinting.This eyewear lens material is hard-coated to resist scratching.
DELTA PHOTOCHROMIC:
Delta Photochromic lenses are engineered to adjust to nearly any light condition. The active molecules are cast into the lens material for quick activation times, extended life, and durability. Spy Delta Photochromic sunglass lenses have one of the widest transition ranges of any photochromatic eyewear lenses on the market.
TRIDENT POLARIZED DELTA PHOTOCHROMIC:
This new, breakthrough sun glass lens system combines Spy’s proven Delta™ Photochromic and NXT® technology with our Trident Polarized filters. The result is an unbreakable, auto-tinting lens that stops over 95% of blinding glare. |

TRIDENT POLARIZED LENSES:
Spy optics manufactures premium injected Trident Polarized sun glass lenses. Trident Polarized lenses diffuse glare through the use of a highly advanced polarizing filter layered within the injected sunglass lens, allowing incredible clarity, even in the harshest enviromental conditions. Spy Trident Polarized PC sunglass lenses effectively eliminate over 99% of blinding glare. All Spy optics polarized lenses conform to the Optical Class 1 system. |

RX:
Spy Optic is pleased to offer prescription sun glasses ordered directly from Surfeyes.com
Available in 6-, 8-,9-base, and 8 x 4 toric wrapped styles. These prescriptions provide proprietary prescription lenses in Spy’s ARC® polycarbonate and Trident polarized lens series. Available in a full range of sunglass lens colors and mirror treatments.
NXT®:
A revolutionary innovation in unbreakable optical polymer technology, Spy Optic’s NXT® lenses resist impact, scratching, chemicals, and atmospheric agents. The superior optical quality, clarity, lightness, and impact resistance provide clear, comfortable eyeglass vision and the highest protection for your eyes. Spy Optic’s current line of Delta Photochromic sun glass lenses are cast in NXT® material.
NXT® is a registered trademark of Intercast Europe S.p.A. U.S. Patents 5,962,617; 5,811,506; 6,258,917; 6,127,505. Other patents pending.
MIRROR COATINGS:
Spy Optics utilizes vacuum-applied mirror coatings that manipulate the light spectrum for maximum visual performance. These sun glass lens coatings are specifically engineered to selectively filter out light waves that cause eye fatigue and discomfort. Spy optics offers a number of coating layers to achieve different colors by absorbing and reflecting different wavelengths in the light spectrum.
UV PROTECTION:
In addition to providing the highest in optical clarity, Spy Optics sunglass lenses provide 100% UV protection (385nm). All Spy Optics lenses, including clear, absorb 100% of UVA, UVB, and UVC rays and provide powerful protection against the harmful effects of solar radiation. Filtering agents are integrated in the sunglass lens manufacturing process and provide eye protection in all conditions.
Ultraviolet rays or UV (100 to 380 nm) are now known to be the most harmful of the sun’s rays. There are three types of UV rays:
* UVA (315 to 380 nm) are the principle cause of aging of the eye.
* UVB (280 to 315 nm) also harmful, cause sunburn.
* UVC (100 to 280 nm) potentially the most dangerous for the eyes, but are filtered by the ozone in the upper layers of the Earth’s atmosphere.
TORIC VS. SPHERICAL:
Think of the lens extending from outside the frame and eventually reconnecting forming a sphere, or circle. This "spherical" lens curve is the lens design you have seen on sunglasses for years.
Now imagine a lens extending outside the frame and eventually reconnecting forming an oval, or egg shape. This new "toric" lens curve lets us design sunglasses with a sleek and modern look. Try a pair on and check out the difference. Of course Spy has engineered the optics utilizing ARC® technology for crystal clear vision. |
