These are one of the most popular styles of glasses; the See-Line SMAC05 Blue w/Tortoise are unique and bold! The full frames, with rectangular lenses, are highly sophisticated with their high grade plastic running throughout the entirety of the frames. The majority of these thick plastic frames show a clear deep blue coloring, while the tips of the arms expose a contrasting tortoise shell hue. A silver colored metal detail is displayed along the temple for extra class! For added convenience, they even come with spring hinges to keep them sharp, and fitting perfectly!
