At present, diving goggles are divided into three materials: rubber, fine rubber, and rubber. Among them, rubber is the most traditional. In comparison, the material is hard and easy to age, but the price is cheaper.
1. Pay attention to water resistance
Each person's face is different, you need to try the selected goggles in person. The specific method is to face down, press the goggles on the eyes, and feel whether the gasket has suction power. Considering the pressure in the water, the suction power at this time should be comfortable and appropriate.
2. Observe the mirror clarity and transmittance
The goggles using the first raw material have the best clarity and are generally more expensive.
4. Anti-fog performance
Because the water around the goggles is cooler, the air in the goggles tends to condense into water on the inner wall of the goggles, thereby causing fogging. Diving goggles with good anti-fog performance, high-tech "eating mist" technology has strong hydrophilicity, can absorb water vapor to form a water film, so that the water vapor cannot attach to the lens to form fog. Moreover, the anti-fog life of "Eating Mist" is long, and it is not easy to melt in water or chemicals.
The design of the diving goggles should follow the principles of ergonomics and actually conform to the anatomical structure around the human face, head and eyes.
At present, the more popular diving goggles in the world are relatively small, because Western eyes are deeply sunken, and small glasses are just embedded in the eye sockets, which is more suitable for Western facial features. Orientals generally have relatively flat faces, so it would be more comfortable to choose a slightly larger goggles. The nose bridge and headband of general diving goggles can be easily adjusted to suit everyone's needs.
