I definitely recommend them.No me llego mi compra creo lo entregaron mal sime lo mandan déjenme en la puertaLove these glasses! My eyes are very sensitive to light and when i wear these... i get the best sleep of my life lets not forget they are stylish! Love them, affordable.. what more can i ask for!I like how thin and easy to wear they are, especially since they are only used for screen time when working off a laptop or computer.Its perfect but in description it says lens width is 54mm but its 51 mmI really love the frame it fits the width of my face.
