I bought some Costco glasses a few months ago and there seems to always be a smudge up in the top corner of the lens by the nose on each lens. I've had them adjusted several times at Costco, but after they are adjusted and cleaned or after I clean them at home, within a few hours the smudge is back. I don't think it's because of my skin hitting the lens. I never noticed the smudges on my old glasses which I got from a different optical company, etc...
I guess I'm wondering if it's because the Costco lenses are of lower quality and so the smudge appears easier or is it because of some other reason? (Adjustment problems with glasses, etc.?)..... it's aggravating that the smudges keep reappearing all the time....thanks for any advice...
