"I have purchased the replacement lenses for Oakleys, as my original ones got scratched both inside and outside. Oakley\'s suggested to send the goggles directly to them for replacement, but since it takes minimum 2 weeks, I decided to give it a try by myself. No regrets at all. The replacements lenses came within 2 days, there was a clear instruction in the box and it took me less than 3 minutes to complete the task. What they do not tell you anywhere is that a replacement lense consist of both outer and inner lens in one, which is great. Definetely cheaper than buying a new pair of goggles! And with regards to the type of lens - Pink Iridium - they are the best for any type of fog/snow conditions or low visibility, but work well with low sunshine as well. For very sunny conditions I use darker lens or sunglassess."
