Viewflau also has a very important feature, because it does not leave traces.
In the questionnaire we did during the research and development process, many female friends thought that the current goggles would leave traces on their faces, which made them embarrassed when they picked them up.
In order to meet this demand, the development team used super soft materials to reduce the pressure on the face, so that the traces will not stay. In addition, gold thread with transparency and luster is installed in the frame part. In the follow-up investigation, this design meets the women's pursuit of beauty. It's really a product for women.
As for the female friends of the original developers, did they communicate with the swimming coach later? Take this as a secret!
