A. Good anti-fog performance: Using advanced anti-fog coating technology, a long-lasting and effective anti-fog coating is inside the lens, which greatly reduces water condensation. Even in a swimming pool environment with a large temperature difference, it can maintain clarity for a long time, allowing you to focus on swimming without frequent wiping of the lens. B. Full-angle view and wide field of view: The unique large frame design, with ergonomic curved shape, breaks through the limitations of traditional swimming goggles and provides an ultra-wide-angle view of nearly 180 degrees, offering a panoramic view of the underwater and surrounding environment. Whether observing the swimming lane during swimming pool training or paying attention to conditions in open waters, it can be easily handled. C. Comfortable fit: The frame is made of soft silicone material, which fits the facial contour tightly, effectively preventing water leakage while reducing pressure on the skin around the eyes. It is not easy to cause marks even if worn for a long time; the adjustable elastic strap can be quickly adjusted to the appropriate tightness according to different head shapes and wearing habits to ensure stability and comfort. D. UV protection function: The goggles are specially designed to effectively filter UVA and UVB rays in the sun, providing all-round protection for the eyes. They are not only suitable for indoor swimming pools but also meet the needs of outdoor swimming, allowing you to enjoy the sun and water without worrying about causing damage to your eyes.
