Using these Mirage junior swim goggles is easy. First, adjust the straps to fit your child's head comfortably. Make sure the goggles sit snugly around the eyes to prevent water from getting in. When putting them on, start from the back of the head and pull the goggles gently over the eyes. Before each swim, rinse the goggles with clean water to keep them clean. After swimming, rinse them again to remove any chlorine or salt. Store them in a cool, dry place, away from direct sunlight. Avoid scratching the lenses. And don't forget to use the bonus earplugs for added comfort. Just roll them up, insert them into the ears, and let them expand to block out water.
