Swimming goggles/swimming goggles introduction/how to choose swimming goggles

Improper selection or use of swimming goggles will not only fail to protect your eyes, but may damage your most precious window to the soul. A pair of swimming goggles with excellent performance is not just about not leaking. To choose a pair of pleasant swimming goggles, you need to consider many aspects.
Optical functions and medical standards
When most people choose orthopedic glasses or sunglasses, they usually go to a professional optical base to make careful selections, and pay more attention to the quality and brand of the glasses. Originally, you should be more cautious when purchasing swimming goggles. Since water and air have different refractive indexes for light, if the surface of the swimming goggles is uneven, it will be like wearing a convex or concave lens in the water, which will cause damage to the eyes and affect vision over time. A good pair of lenses should meet optical and medical standards, have stable power above and below the water, have clear and undistorted vision, and have a broad field of vision.
Comfort
The design of swimming goggles should follow ergonomic principles and actually fit the anatomical structure of the human face, head and eyes. Currently, the more popular swimming goggles in the world are smaller. Because Westerners have deep-set eye sockets, small glasses fit right into the eye sockets, which is more suitable for Westerners' facial features. Orientals usually have flatter faces, so they will be more comfortable if they choose slightly larger swimming goggles. Generally, the nose bridge and headband of swimming goggles can be easily adjusted to suit everyone's needs.
Appropriateness
Swimming enthusiasts often have similar embarrassing experiences. When they stand on the starting platform with confidence and jump into the water proudly, just when they are about to compete with their brothers, they find that they are wearing the same clothes. The good swimming goggles have disappeared, maybe they have become a collar hanging around my neck, or maybe they are leaking. In addition to the fact that the swimmer's starting skills need to be improved, the proper function of the swimming goggles itself is also very important. The main factors that determine the proper function of swimming goggles are whether the frame and eye mask fit closely with the eye sockets, whether the length of the nose bridge is appropriate, and the elasticity and quality of the headband. The silicone headband has excellent elasticity, and the anti-slip points on it can effectively prevent the swimming goggles from falling off or sliding.
Anti-fog function
Since the water around the goggles is cooler, the air in the goggles can easily condense into water on the inner wall of the goggles, causing fogging. Swimming goggles with excellent anti-fog performance, the high-tech fog-eating technology is highly hydrophilic and can absorb water vapor to form a water film, so that water vapor cannot adhere to the lenses to form fog. Moreover, the anti-fog effect of Chiwuzi has a long service life and is not easily dissolved in water or chemicals.
Appearance and Packaging
With the improvement of people's living standards and the rise of individual personality, the function of swimming goggles is not only limited to eye protection, but also should be able to meet fashion and aesthetic needs. Just like clothing, different groups of people, on different occasions, wear different swimsuits and wear swimming goggles with different personalities in a selective manner.
Myopia
Myopia patients usually find it difficult to walk once they take off their glasses. If you wear contact lenses while swimming, it is easy to cause eye infection, and once you accidentally lose them in the swimming pool, it will be extremely difficult to find them again. Therefore, it is recommended that myopic patients choose swimming goggles with corresponding degrees. Myopia swimming goggles are basically made of plastic reinforced steel, polycarbonate, silicone and other types, and have added functions of waterproofing, fogging and UV protection.
