The development team actually observed the process of children using swimming goggles. Through the understanding between the people he knew and the headmaster there, a questionnaire survey was carried out for the students, and their interests and preferences were analyzed in detail.
However, even in this way, no information about the functions of swimming goggles that children want can be obtained.
One day, when the developers saw the children swimming hard, they thought of their school days: "I also worked hard at that time, but the goggles were tossed around and used very hard."
Then, the developers began to observe the children's action of using swimming goggles. In the process, I found that if they continue to use the wrong size goggles, the lenses will be damaged first. If they use the damaged goggles all the time, they will not have good eyesight for children for a long time. And it's an adult perspective that kids don't feel.
Therefore, the development team decided to develop a goggle with no damage to the lens. After trying, we finally developed the goggles that will not be damaged even if they land on the ground.
