If you are looking for a kit that can give you all the eyewear protection you need, try the ESS Ice Eyeshield Deluxe Medium Large Fit LE Sunglasses Kit. This kit is designed with law enforcement agencies in mind. The current configuration allows you to spend less time changing lenses, so you can focus on the mission at hand. Additionally, because the process of changing lenses has improved, the glasses are more protected against wear and tear. Despite the alterations, this Ice still has the classic lightweight and frameless construction as earlier models. This means your field of vision will remain unobstructed.
