I purchased this product to replace the Bolle Parole Competitivision glasses. Competitivision lenses are perfect for playing tennis -- increased visibility of the ball, reduces glare, not too dark on overcast days. Lenses are fixed and don't fall out. Mirror finish is great for bright days. Ear pieces are constructed of better materials than Parole model. All the women on my tennis team ordered these glasses after seeing mine.
