If you're an athlete or just on the go, these rimless glasses by Dxtreme will protect your eyes under any condition through any challenge. The frames are plastic and sport a ribbed pattern on the interior for better fit and grip. The arms are straight with no taper or curve, giving the glasses a sleek look and an aerodynamic fit. The lenses are rectangular and fit in the front of the semi-rimless frame with a nosepiece to keep them snug. The glasses are available in multiple lens and frame colors.
