These XLoop kids sunglasses are really cute! They are strong and have sufficient give so that the little ones won't snap them in half it they are playing with them.  The nose piece is part of the frame and not rubberized so it is smooth and won't irritate children's noses. The arms of the glasses are straight and rest gently on top of the ears; these are rubberized to prevent them from slipping off of their face when they look down which is very helpful because kids never sit still.  The entire frame and the lenses are a shiny dark black.  I think it is especially important to have sunglasses on children to protect their eyes from the harsh rays of the sun.  It is really nice that they come in a bag so they are protected from scratches when not in use and the bag doubles as a cleaning rag that is safe enough to wipe little fingerprints off of the lenses  I received this product for free in exchange for my honest, unbiased review.
