The breathability of sunglasses is mainly related to the design of the frame, the selection of materials and the wearing method. The analysis is as follows:
Frame design: The fit of the frame is closely related to its breathability. If the frame is designed too tightly against the face, it will impede air circulation, causing a stuffy feeling when worn. On the contrary, frames with open or hollowed-out designs can increase the space for air circulation and enhance breathability. In addition, the design of the temple legs also affects breathability. For instance, temple legs made of elastic materials or with adjustable structures can better adapt to different head shapes, reduce the pressure on the head, and thereby indirectly enhance breathability.
Material selection: The materials of the frame and temples have a direct impact on breathability. Some lightweight and breathable materials, such as TR90 and other polymer materials, have good elasticity and breathability, which can reduce the stuffy feeling when worn. Meanwhile, these materials also have the advantages of impact resistance and wear resistance, making them suitable for long-term outdoor activities.
Wearing method: When wearing sunglasses, if there is an appropriate gap between the lenses and the face, it can increase air circulation and improve breathability. In addition, regularly cleaning sunglasses to keep the lenses and frames clean can also help improve breathability, as dirt and grease may block the channels for air circulation.
