Our Uvex glasses are specially designed with safety frames that allow the wearer to adjust the length of the ear wire and the angle of the front lenses, providing closer contact with the zygomatic and maxillary areas of the face. Our RayShield® NewMillenia™ lightweight composite 0.5mm or 0.75mm lead equivalent lenses provide excellent front protection with 0.25mm solid lead side shields. Close contact with the face also provides added splash protection.
