How transparent are the lenses? Looking for mirrored so you can't see eyes

The lenses are mirrored but they still look very nice! In fact they are beautiful sunglasses. You can't see your eyes through the lenses and if that is your question I would say "no". But I do love these sunglasses and they filter out all the suns rays when I am driving the car. Hermina
