It can depend a little on the particular model and lenses, since some are hydrophobic and easier to clean, etc. You can generally wash any sunglasses with tap water and mild soap if you have need, but that's not a daily occurrence for most. If you have hard water you may want to be a little more careful to avoid mineral buildup and dry them right afterward.
Your biggest concerns are the obvious -- don't drop them, don't sit on them, don't leave them lying around outside of a case when you don't need to.... Beyond that, you mainly need to beware not to scratch the lenses, especially with many Oakley Sunglasses Wholesale.This is most likely to happen when you wipe them, and why Oakley says to use only their microfiber cloths and cases to clean them.
However, you still need to be careful of dust particles on the lenses you might smear around, and you can even have dust sitting on your cleaning cloth after it's been used a couple times. What you really don't want to do is wipe the lenses carelessly with your average shirt sleeve or something.
I personally buy compressed air in bulk from Costco along with the Wipe n Clear lens cleaning cloths they carry (though use both for other things too). Whenever I go to clean my Oakley Sunglasses Cheap 90% Off -- usually after lots of exercise -- I use the compressed air briefly to get rid of any dust and dirt, then the pre-moistened cleaning cloths to wipe them clean, and I'll sometimes then use the Oakley cloth/bag to touch up any final spots that might be left from drying.
Only rarely do I find it necessary to run something under water. The moistened lens cleaning cloths work fine for lenses and frames in most scenarios.
