Anti-fog coating and UV protectionThe children's swimming goggles are designed with an anti-fog coating inside, so you can have a clear view when swimming underwater without worrying about your glasses fogging up and affecting your vision. The goggles come with UV protection to protect your eyes from UV damage. Please do not touch the inner surface of the lenses with your hands or sharp tools, as this will damage the lenses and destroy the UV protection and anti-fogging function. Quality Silicone FrameThe children's swimming goggles are made of soft silicone frame, which can relieve the pressure on the skin when wearing and seal better to prevent the glasses from leaking. The soft nose clip allows kids to feel comfortable wearing them without hurting their noses. The silicone frame has good stretching properties, making the frame less prone to damage. One Touch Wear When kids wear them alone, they can easily use the adjustable elastic band to quickly put on the goggles without tangling their hair, just press the buckle and pull the band to quickly adjust the elastic band. The elastic band of the goggles has good elasticity and can withstand strong pulling force, suitable for most children's heads. 3D Humanized Design The 3D ergonomic design of the children's swimming goggles allows the goggles to fit your child's eyes perfectly and achieve a perfect fit.
