I never go out in the sun without my sunglasses.  I do this on the advice of my eye doctor because he says that the direct rays of the sun can be harmful and cause cataracts.  I also like to wear a variety of sunglasses so that people will not always see me in the same ones.   At the cost of designer sunglasses today I would not be able to afford many pairs if I had not discovered where to purchase wholesale sunglasses.  Now for a reasonable investment I can have a different pair for every occasion and not have to one the same pair twice in a week
