1st Glance: Packaging & instructions were great and provided value. Easy to follow along and replace lenses and even came with a new pouch for my shades.  One strange thing I noticed and maybe it was just me. When walking with the sun in my face I started to get a slight headache or a dull pain behind my eyes.  I'm not sure if the sun was too bright for this specific polarization but it reminded me of wearing an incorrect prescription of glasses.  Once sitting and reading at the pool, I no longer noticed this issue.<br /><br />4 Weeks In: Starting to notice some a whole bunch of tiny spec marks out of the front of the lenses. I am not noticing a loss in the quality of my vision but from up close they do not look like they did when I purchase these. I clean these with a cleaning kit from Sun Glass hut (where I purchased my other Oakley's).  I haven't seen this isse with my other sunglasses which i've had for a few months longer.
