They did not fit over my glasses at all, and kept falling down. I returned them.
In a previous posting I alluded to how I loved the sunglasses but only received one pair. I was later contacted by customer service and informed how I had overlooked the Bogo Alert and that is why only one pair was shipped. They acknowledged my error and, as good customer service goes, agreed to send me a second pair.
These glasses are so comfortable and the fit is perfect with a grip around the ears! Love
