Kenyonwrote a review of Oakley M Frame Heater Replacement Lenses on February 10, 2004
I'm a professional carpenter and depend on my glasses to not only protect my eyes from the sun, but also any projectiles such as flying nails and wood and metal fragments. I've tried many different glasses and none offer the comfort, coverage and variety of lenses needed to get the job done in any conditions. I can wear these glasses all day and forget that I even have them on. The are definitely worth the money - far cheaper than a visit to the emergency room.
