is it possible that cleaning your lenses too much will actually hurt them? i work in construction, which can be rough on a pair of glasses. so i only wear my oakley's on the weekend (friday-sunday). i will usually wear them throughout the weekend, lightly buffing them with the microbag between uses. then sunday night, i always clean them with the cleaning kit since they will sit all week. i dont want them to sit all week with skin oils, and dirt resting on them. they usually dont get very dirty. mainly just skin oils and a little sweat. do you guys think i'm over cleaning them by cleaning them once a week?
