High-definition sunglasses lens technology mainly involves polarizing technology, lens material, UV protection and coating technology. The following is a detailed analysis of these technologies:
Polarizing technology
High-definition sunglasses lenses usually adopt polarizing technology. This technology blocks random reflected light, such as water surface, snow, and road glare, through a special filter layer, thereby reducing eye fatigue and enhancing contrast. The working principle of polarized lenses is similar to that of blinds. They can block light from a specific direction and only allow the reflected light of the object itself to enter the eyes, making the field of vision clear and natural. This feature makes high-definition polarized sunglasses particularly suitable for outdoor activities that require clear vision, such as driving, fishing and skiing.
Lens material
The materials of high-definition sunglasses lenses are diverse, with common ones including polycarbonate (PC), nylon, resin, etc. These materials each have their advantages and disadvantages:
Polycarbonate (PC) : High strength, excellent impact resistance and scratch resistance, lightweight and durable, suitable for high-intensity outdoor sports. However, the surface is prone to scratches and the price is relatively high.
Nylon: It features high elasticity and excellent optical properties, strong UV resistance, superior chemical resistance, light weight, strong impact resistance, and is not prone to cracking. However, the price is relatively high and the surface is prone to dust and fingerprints.
Resin: Lightweight and has good impact resistance, suitable for long-term wearing. However, it is prone to scratches and requires proper maintenance.
UV protection
High-quality high-definition sunglasses lenses usually have 100% UV400 protection, which can block UVA/UVB ultraviolet rays and protect the eyes from long-term sun damage. UV protection is one of the basic functions of sunglasses lenses and is crucial for safeguarding eye health.
Coating technology
High-definition sunglasses lenses may also adopt technologies such as anti-reflective coating and water-resistant and oil-resistant coating. Anti-reflective coating can reduce internal reflection within the lens and improve visual clarity. The waterproof and oil-proof coating can make the surface of the lens smoother, less prone to water stains and oil stains, and easier to clean and maintain.
