These glasses are fine - no problem.  I own a pair of Oakley's which are much better and very much more expensive.  Nevertheless you will not be disappointed with these glasses.  I purchased a pair with clear lens as i like to ride at 5 AM when it is still dark and cool here in Florida.  I was cheaper to purchase these than clear Oakley lenses.  So buy them and you will not be disappointed.  The reason for 4 stars is that i asked a question about he dual lenses and many said their glasses came with extra lenses.  Mine didn't.  I don't know why but i am satisfied anyhow.
