The sand-proof design of sunglasses

The anti-sand and dust-proof design of sunglasses is mainly reflected in multiple aspects to deal with the potential harm to the eyes in the complex outdoor environment:

One-piece large lens design: It adopts a one-piece formed large lens, which can expand the field of vision, and at the same time reduce the gap between the lens edge and the face, lowering the risk of sand and dust entering the eyes. This design can also effectively block sandstorms, mosquitoes and splashes, making it suitable for outdoor activities such as cycling and hiking.

Temple adjustment function: The temple supports length and Angle adjustment, which can adapt to different head shapes and enhance wearing stability. Some designs further reduce the possibility of sand and dust entering through the gap between the frame and the face by widening the forehead area or adding anti-slip patterns.

Windproof and dust-proof frame structure: The frame adopts an arc-shaped design that fits the facial contour, combined with the anti-slip material of the nose pad and elastic temple legs, forming a sealed protective layer. This structure can not only prevent sand and dust from entering, but also avoid scratches on the lenses caused by wind and sand friction.

Anti-fog and anti-fouling coating: The surface of the lens is coated with an eight-layer coating process, including an anti-oil stain coating layer and an anti-reflection coating layer. The former can reduce the adhesion of fingerprints and oil stains, while the latter can lower the glare reflection in complex lighting environments, maintain the cleanliness of the lenses at the same time, and indirectly enhance the anti-sand and dust effect.

Material and durability: The frame is made of highly elastic and tough material, which is impact-resistant and not prone to deformation. The lenses are made of lightweight and impact-resistant materials such as nylon, which not only reduces weight but also enhances durability. This combination ensures that it can maintain protective performance even after long-term use in a sandy and dusty environment.
