Purchased the Oakley Radar Path Polaroid Sunglasses with the motivation was to have some nice polarized sunglasses to wear during my outdoor activities.  The retail price is USD $250.00, which is a lot, but having the ability to protect your eyes from the sun and flying harzards was worth almost any amount.

Overall, we really like these sunglasses.  They have a special coating and lens design that allows perspiration to slide right off. They still fog up when running in the high humidity.  We noticed some slight aberration at the periphery, but not enough to distract us.

For Top 100 Adventurers and Bucket Listers, the Oakley Radar Path Polaroid Sunglasses come highly recommended.
