Adult swimming goggles need to maintain a good sealing effect under the impact of water flow and prevent water leakage. The design of its sealing structure and the selection of materials play a key role. From the frame that fits the face to the stable goggles, each part cooperates with each other to build a reliable waterproof barrier.
The frame of adult swimming goggles is the basic component to achieve sealing. The frame is mostly made of soft and elastic silicone material. The biggest feature of this material is that it can be adaptively adjusted according to the facial contours of different users. When the swimming goggles are worn on the face, the silicone frame will be like a soft "protective film" that fits the skin around the eyes tightly. Whether it is high cheekbones, wide foreheads, or relatively flat faces, the silicone frame can naturally deform along the curve of the face, fill the gap between the face and the frame, and leave no chance for water to penetrate, thus forming the first effective sealing defense line.
The skirt design in the sealing structure further enhances the waterproof ability. The skirt edge of the frame has been specially widened and thickened, and compared with ordinary designs, it has a larger contact area with the face. A larger contact area means a stronger suction force, just like a suction cup tightly attached to a smooth surface, which firmly fixes the swimming goggles on the face. During swimming, even if you encounter strong water flow impact caused by fast swimming or changes in water pressure during diving, the widened skirt can maintain a stable fit, effectively preventing water from invading from the edge of the frame, and ensuring that the eyes are not irritated by the pool water.
The connection method between the goggles strap and the frame also has an important impact on the sealing effect. The goggles strap of adult swimming goggles is usually tightly connected to the frame, and a reinforcement design is used at the connection part. This design allows the tension applied by the goggles strap to be evenly distributed to various parts of the frame, ensuring that the frame always fits the face evenly. When the user adjusts the tightness of the goggles strap, the frame will not be too tight or too loose in some parts, but will fit tightly to the face with appropriate pressure as a whole, avoiding poor sealing of some parts due to uneven force, thereby preventing water from seeping in from the gaps.
In addition to the frame and goggles strap, the nose bridge of the swimming goggles also plays a role in sealing. The design of the nose bridge takes full consideration of ergonomics, and its length and width are carefully designed to fit the nose shapes of different users. A suitable nose bridge allows the frame to fit more accurately around the eyes, avoiding the frame from tilting and damaging the sealing structure due to an inappropriate nose bridge. At the same time, the nose bridge is also made of soft material, which ensures a firm connection between the frames on both sides without causing pressure on the nose, ensuring that the sealing structure of the entire swimming goggles remains stable and is not easily damaged during swimming.
Some adult swimming goggles also have a unique drainage design, which is an important supplement to deal with unexpected water seepage and ensure the sealing effect. When a small amount of water accidentally enters the swimming goggles, the drainage design can quickly drain the accumulated water. For example, some swimming goggles have tiny drainage holes on the edge of the frame. The position and size of these drainage holes are specially designed to ensure that water will not flow back into the swimming goggles due to water pressure when they are worn normally. When water seepage occurs, the gravity of the water flow and the inertia of the movement can be used to quickly drain the accumulated water, so that the inside of the swimming goggles remains dry and prevents the accumulated water from affecting the vision. At the same time, it also avoids the destruction of the overall sealing balance due to excessive water accumulation, further enhancing the ability of the swimming goggles to resist the impact of water flow.
In the actual production process, strict quality inspection procedures ensure the reliability of the sealing structure of each pair of adult swimming goggles. Manufacturers will conduct multiple waterproof tests on swimming goggles, simulate water flow impact and water pressure environments of different intensities, and check whether the swimming goggles have water leakage. Only swimming goggles that pass all strict tests will enter the market, which guarantees from the source that the adult swimming goggles purchased by consumers have a sealing structure that can effectively resist water flow impact in various swimming scenarios, provide users with a dry and clear visual environment, and allow swimmers to enjoy the fun of swimming with peace of mind.
