Oakley Flak Beta Glasses

They also feature a three-point fit that ensures precise optical alignment, yet also eliminates any pressure points.

The frame is constructed using Oakley's O Matter (TM) material, which is lightweight, stress-resistant, and offers day-long comfort.

Technologies:High Definition Optics (R) : HDO (R) is a collection of patented technologies that allows Oakley eyewear to meet or exceed the testing standards of the American National Standards Institute for optical clarity, visual fidelity, and impact resistance.

HDO (R) provides superior optical clarity and razor-sharp vision at every angle.Impact Protection: Backed by decades of innovation, Oakley performance eyewear offers uncompromising protection against high-velocity and high-mass impact.

The protection is a benefit of the premium materials and unique architectures of Oakley lens/frame combinations.XYZ Optics (R) : Oakley lenses are cut from a single sheet of material along the same axes to ensure they are in perfect optical alignment. Oakley also tapers the lens thickness from the centre to the edge giving lower light refraction at the periphery and compensating for the overall prismatic effect of the lens curvature.

This shaped lens not only provides greater clarity but also helps reduce eye strain.Unobtainium (R) : An innovative hydrophilic material that readily absorbs water and doesn't become slippery when wet. Oakley uses Unobtanium on nose pads and ear socks of its glasses to increase 'tackiness' as athletes perspire so the glasses stay in place even in hot, sticky conditions.

O-Matter (TM) : This stress-resistant frame of nylon-infused plastic is lightweight, durable and can withstand heat and cold without becoming brittle.

The flexibility enhances impact resistance and helps to make these glasses more comfortable to wear for long periods. Because O-Matter is also less rigid than other plastics, it shapes better to the head.
