Head Down Training Glasses is a great fielding training aid.  The training glasses, worn like other glasses improves a fielder’s ability to catch ground balls keeping the fielder’s head down on the ball, all the way into the glove, dramatically improving the players glove hand responsiveness. The arms are ergonomically designed for greater comfort and molded TPR arm tips provide for a soft comfortable fit. TPR nose pads are also used for greater comfort and impact protection. Head Down Training Glasses are also great for hitting and are available in youth and adult sizes.  I buy a set for each player on my teams every year - I love these glasses.
