The Oakley Eyeshades tunnel right back to the roots of Oakley's beginnings. The first edition was released in 1984 and resembled a blend of ski goggle lenses integrated with eyeglass earstems. Now, to celebrate nearly 30 years of what has become a staple in sports eyewear, Oakley has revisited the past with its Heritage Collection. Rather than just pulling out old stock, Oakley relied on the same Eyeshade design but updated it to the standards that has made it a household name in eye protection. To begin with, the lenses received Oakley's proprietary HDO High Definition Optics. These optics provide three things. First, you see images clearer and sharper without any image distortion. Second, regardless of the curvature of the lens, images appear where they actually are, instead of being shifted. Finally, HDO lenses are impact resistant and filter 100 percent of UV rays. The frames themselves were constructed from high impact O Matter, so you won't have to worry about them shattering should you take a tumble. The Oakley Eyeshade Heritage Collection Sunglasses are available in one size and in three colors: Blackgrey, Foggrey, and Seafoamgrey.
