I truly love these glasses!  They have such a retro feel to them and the rimless frames look so cool.  My Mom has already tried to take these from me but I think I will be keeping these for myself.  They fit great and feel very comfortable on my face.  The plastic frame and plastic lenses are very lightweight.  The glasses are non-polarized but do offer 100% UV protection.  Impressed by the style and quality.  Sample provided for testing, evaluation and review.
