Excellent fog performance: Utilizing advanced anti-fog coating technology, a long-lasting and effective anti-fog layer is applied inside the lens, which greatly reduces water condensation. Even in a swimming pool environment with a large temperature difference, it maintains clear vision for a long time, allowing you to focus on swimming without frequent wiping of the lens. Full-angle view and wide field of view: The unique large frame design, combined with ergonomic curvature, goes beyond 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 pool training or monitoring conditions in open water, it can be easily managed. Comfortable fit: The frame is made of soft, medical-grade silicone material, which fits tightly to the face, effectively preventing water leakage while reducing pressure on the skin around the eyes. It is not likely to cause marks even when worn for extended periods. The adjustable elastic strap can be quickly adjusted to the appropriate tightness according to different head shapes and wearing preferences, ensuring stability and comfort. High-quality and durable material: The entire product is made of high-quality materials. The goggles have good impact resistance and are not easy to break, able to withstand accidental collisions during daily use. The frame and lens are sturdy and durable, resistant to wear and scratching. Even with frequent use and long-term storage, they maintain good performance and appearance. Function: The goggles are specially designed to effectively filter UVA and UVB rays from sunlight, providing all-around protection for the eyes.
