I've purchased Zenni glasses for my last 2 prescriptions. The first pair I got I found much more comfortable after replacing the nose pads with a kit from Walmart. Otherwise the glasses are pretty good - lightweight, double hinged and everything.

I reordered the same frames this past year and they seem to be fine, so I don't know if they changed up the nose pads in any way or if I managed to adjust the frames properly this go around.

For sunglasses I go with with Luxottica because of the premium polarized lenses. I wear sunglasses 11 months out of the year so I definitely agree on getting a quality pair.
