The first thing I noticed is that the glasses are heavy. No cheap plastic, here. A lot of the construction is metal, and it shows. Flex-springs at temples allow for larger-headed people's comfort. Upon putting them on, I felt that colors were altered in a strange way. Maybe it's the polarization, or maybe it's the tint, but it seemed that all of the duller colors in my vision were made darker and the vibrant greens, blues, pinks, reds, and oranges stood out more. It's something to get used to.
