OAKLEY, OAKLEY, OAKLEY, OAKLEY The only sunglasses that I will wear or put on my wife or daughters eyes. I have seen the specs that they make their glasses too and tests that compare all the others to Oakley. I wont bore you with the details but here are a few facts. 1. Lens is cut out of the center of the lens material, which is the best part of the mold. The rest is trashed or bought by other companies. They are never used again by Oakley. 2. The pair (Left and Right) stays together throughout the process and go into a frame together. Other companies stamp a bunch or left and rights and then mix and match when they are put into frames. 3. Ballistic standards are the best in the industry. Oakley also focuses on the ballistics of the frame. If the frame fails what good are your glasses in protecting you? If you are experiencing headaches after wearing sunglasses your sunglasses are causing eye fatigue. Your glasses are distorting the image and/or shifting the image you see. 10 times a second your eyes are trying to refocus or recenter that image, causing eye fatigue and headaches. Oakley exceeds the standard in this area. For those that are curious check this link to learn more. http://oakley.com/innovat…l_superiority/hdo/proven By far the best sunglasses on the market. If anyone gets a chance to visit the factory or the rolling O lab I suggest it highly. Bring your favorite pair of glasses and see how they compare.
