When your child is engaged with high-contact physical sports, you need to do everything in your power to ensure his or her safety. One way to achieve this is with kids sports glasses. Protective eyewear helps to shield your little one from flying elbows, renegade ball or any other dangers on the field. When you see the ASTM F803 designation on a pair of glasses, it means the eyewear has gone through rigorous quality tests. The American Society for Testing and Materials provides this rating to eyewear that meets industry impact standards for sports.
