Using these swim goggles is a breeze. First, adjust the adjustable nose pieces to fit your child's face comfortably. Then, place the goggles over your eyes and use the easy - on back clip to secure them in place. When your child is done swimming, remove the goggles gently. Remember, these goggles are for swimming only, so don't use them for other activities. To keep them in good condition, rinse the goggles with clean water after each use and store them in the hard protective case provided. This will protect the lenses from scratches and keep the silicone in good shape.
