Oakley Flak Jacket Prescription Sunglasses - Jet Black / Grey

Sport professionals demand nothing less than the best, and Oakley have answered their challenge for decades. World-class athletes have driven Oakley to create innovation after innovation, including interchangeable lens designs with unbeatable optical clarity. Flak Jacket takes that to the next level with the latest in performance technology.

Maintains sharp, clear vision
Flak Jacket sunglasses feature Oakley Hydrophobic™, a permanent lens coating that prevents rain and sweat from building up on the lens. It also repels skin oils and other contaminates, so the lens is smudge resistant and easy to keep clean. It even eliminates static electricity, so dirt and dust particles won’t cling.

Offers a secure custom fit
Choose the nose pads that give you the best fit — two sizes are included with every frame. Like the stem sleeves, they’re made of Unobtanium® to increase grip with perspiration. Oakley’s Three-Point Fit optimises comfort and holds the lenses in precise optical alignment for superior clarity.

Optimises comfort, protection and clarity 
Flak Jacket is made of lightweight O Matter® for all-day comfort. Pure Plutonite® lens material filters out 100% of all UV, and Flak Jacket meets ANSI Z87.1 standards for impact protection. The semi-rimless design means there’s no frame rim to block downward view. Optical clarity exceeds all ANSI Z87.1 standards, and XYZ Optics® extends razor-sharp vision all the way to the lens periphery.

• Interchangeable lenses to optimize performance in any environment
• Durability and all-day comfort of lightweight, stress-resistant O Matter® frame material
• Optimized peripheral vision and side protection of 8.75 base lens curvature
• Comes standard with Oakley Hydrophobic™/Oleophobic anti-smudge lens coating on all lens options
• Comfort and performance of Three-Point Fit that holds lenses in precise optical alignment
• Metal icon accents
• Optical precision and performance that meets all ANSI Z87.1 standards
• Impact resistance that meets all ANSI Z87.1 standards for high-mass and high-velocity impact
• UV protection of Plutonite® lens that filters out 100% of UVA / UVB / UVC & harmful blue light up to 400 nm
• Multiple interchangeable Unobtanium® nose pad options for customisable and comfortable secure fit
• Protective sports-specific Oakley Soft Vault included with capacity for extra lenses

Oakley Eyewear Technology

Oakley True Digital

Traditional lenses in high-wrap frames frequently cause the wearer’s peripheral vision to blur and distort. Naturally, such shortcomings just don’t fly for cyclists, runners, and motorsports enthusiasts and the other world-class Oakley athletes who rely on their peripheral vision to maintain competitive advantage. Oakley engineered TrueDigital lens technology specifically to address these issues, and the results are:

• Sharper peripheral vision
• Eliminated distortions
• Exceptional visual clarity
• Vastly improved optics without compromised style

High Definition Optics (HDO)

Proprietary geometries, high performance materials and state of the art design and production techniques allow Oakley to create sunglasses that maintains optical correction for refractive power, optical clarity and prismatic power. These three classifications are measured by a global stndard ANSI Z87.1 for optical performance ratings. Oakley is the gold standard and best in class, as evident in Private Pilot'magazine's sunglasses test results comparing all eyewear manufacturers.

Impact Protection

The lens materials and frame geometries of Oakley sunglasses provide unsurpassed protection against high-velocity and high-mass impact. For high-velocity impact testing, a quarter-inch steel shot is blasted froam a pneumatic cannon at 102 mph / 164 kmh. The high-mass impact test uses a metal spike (more than half a pound of weight / half a kilo) dropped from over four feet. The unique combination of wrapped, raked-back lens geometries and durable Plutonite lens material lens material allows Oakley eyewear to exceed the standards of these impact tests, established by the American National Standards Institute.

UV Protection

Oakley sunglasses provide unbeatable protection against the damaging rays of ultraviolet radiation. The Oakley Plutonite lens material inherently blocks 100% UVA, UVB, UVC and harmful blue light. The protection is formulated into the lens material, as opposed to a thin surface film that can become scratched, leaving dilated pupils exposed to ultraviolet leaks. Shielding has nothing to with the darkness or colour of the lens, so even clear Oakley lenses provide full protection. The wrapped, raked-back architecture of Oakley sunglasses provides further protection by blocking UV from the periphery.

Plutonite Lens Material

Lightweight Plutonite lens material offers superior comfort, clarity and protection against impact and ultraviolet radiation. Maintaining the proven safety charateristics of Oakley sunglasses, the impact-resistant material blocks 100% of all UVA, UVB, UVC and harmful blue light. Plutonite is the only lens material able to achieve the performance standards required by the digital design and production technologies utilised by Oakley.

Three-Point Fit

Oakley sunglasses are engineered to maintain a comfortable, secure fit. The company's patented Three-Point Fit ensures that each frame makes contact only at the bridge of the nose nd behind the temples. This retains optics in perfect alignment and eliminates the discomfort of ordinary frames that hook the ears and mount with unbalanced pressure points. Some earstems are sheathed in Unobtainium, an Oakley innovation that actually increases grip with perspiration.

Frame Composition

Engineering breakthroughs in structural materials allow Oakley to produce lightweight, high performance sunglasses that maintain superior protection and comfort. The polymers in O Matter sunglasses are formulated for high durability, as well as controlled flexibility for improved safety during impact. To produce the ultra-strong, ultra-lightweight chassis of Oakley wire frames, five metallic compounds are fused into a cingle C-5 alloy. Both frame materials maintain resistance to ultraviolet radiation, humidity, thermal shock and chemical exposure.
