Since I have migraines all the time, these will come in very handy. I need dark glasses to block out most of the light, especially if I am trying to drive. These are super dark glasses and I love them! They are not polorized so they don't mess with me using my phone or computer. I find these easy to work with. They are a very sturdy frame made out of a composite type of plastic. They block the harmful rays of the sun UVA/UVB and they come with a cleaning cloth and storage bag. All in all a very nice pair of glasses! I would recommend to all my friends!
