Sunglasses with plastic frames are generally the least expensive. There are several types of plastic frame materials, the most common type being zylonite. Zylonite (zyl) frames are easily adjusted with heat and are available in a variety of colors. Another popular plastic frame material is polycarbonate. Polycarbonate frames are primarily associated with sport or safety glasses, as they offer optimum impact resistance and eye protection.
