The drain valve design for adult swimming goggles achieves a significant improvement in drainage efficiency through structural simplification, location optimization, and material upgrades.
During use by children, the lenses often collide with swimming caps, hair, or pool walls, and microscopic damage caused by scratches from fingernails can disrupt the continuity of the coating.
In a pool with moderate lighting, smoky colors can filter out harsh direct light while retaining enough light transmittance to ensure a clear view.
Silicone sealing rings will lose elasticity after long-term use, but users often find it difficult to intuitively judge when to replace them.
During a child's first encounter with the water, a properly fitted pair of children's swimming goggles often determines whether they experience swimming with fear or curiosity, resistance or love.
In adult swimming, goggles are not only essential equipment for protecting the eyes and enhancing underwater vision, but also a key factor influencing overall swimming experience and performance.
