I got a pair for Christmas. I love them. They are a bit heavy - wearing two pair of glasses but the lenses are good quality and the frame is meant to cut out glare that comes from the sides. There is also the drawback of wearing two pair of glasses with lessened ventilation on a hot humid day. You can get a cheaper pair from Walmart in the States I do not know if they are the same quality ( google fitovers and you will find cocoons and the walmart brand are made by the same company. I inquired at walmart in Canada they do not carry them).
Hope this helps
