This swim goggles kids are carefully designed in terms of material and performance to ensure that children are safe and comfortable to wear. This set of swimming goggles uses a soft one-piece silicone nose mask that gently fits small faces, helping beginners overcome their fear of water and enjoy every dip in the water with peace of mind. Questions & Answers Q:Why do goggles fog up? Poor seal around the eyes: If the silicone frame doesn't fit snugly against the face, water leaks in and causes fog. Simply adjust the strap and nose bridge until the goggles sit comfortably and securely against the eyes. Damaged anti-fog coating: Goggles come with a pre-applied anti-fog coating on the inner lens. To keep it working, just rinse the lenses quickly in water before use. Do NOT rub the inside with fingers, cloth, or any material — this will damage the coating and cause fogging. Tips: The surface of the swimming goggles has been treated with anti-fog treatment. After use, wash it with clean water and shake off the water. After wearing goggles, the facial muscles should not be moved too much to avoid water leakage. Prolonged anti-fog effect should be stored in a dry place. The nose buckle and mirror strap should be properly adjusted before use. Do not wipe the mirror surface with a towel to prevent damage to the mirror surface. If there is any abnormality in the eye area during use, discontinue use.
