Tips for choosing polarized sunglasses

Lens material | Very important

Recommended choice: NXT polyurethane > TAC > CR-39 > Polycarbonate (PC)

Popular science explanation: NXT polyurethane lenses have excellent optical performance, impact resistance and scratch resistance, so they are superior to other materials in optical performance and durability. TAC lenses have excellent optical performance and scratch resistance, suitable for daily and outdoor use. Although CR-39 lenses have good optical performance and are lightweight, they are not as durable as NXT and TAC. Polycarbonate lenses are impact-resistant and suitable for sports and outdoor activities, but their optical performance is slightly inferior.

Polarization technology | Very important

Recommended choice: Multi-layer polarizing film > Single-layer polarizing film > Ordinary polarizing film

Popular science explanation: Multi-layer polarizing film can more effectively reduce glare at different angles, provide higher visual clarity and comfort, especially in highly reflective environments such as water and snow. Single-layer polarizing film can effectively reduce most glare, but the effect is slightly inferior to multi-layer. Ordinary polarized film layers have limited effect in reducing glare and are less applicable.

UV protection | Very important

Recommended choice: UV400 > UV300 > No logo

Popular science explanation: UV400 protection can block 99-100% of UVA and UVB rays, providing the best eye protection and avoiding UV damage. UV300 protection can only block part of the UV rays, and the protection effect is not as good as UV400. Unmarked lenses may not effectively protect against UV rays and pose a greater safety hazard.

Lens color | More important

Recommended choice: Gray > Brown > Green

Popular science explanation: Gray lenses can maintain the natural balance of colors, reduce eye fatigue, and are suitable for most lighting conditions. Brown lenses can enhance contrast and improve visual clarity, especially suitable for driving and outdoor activities. Green lenses help reduce eye fatigue and are suitable for long-term wear, but in some cases the contrast is not as high as brown lenses.

Frame material | More important

Recommended choice: TR90 > Titanium alloy > Stainless steel

Popular science explanation: TR90 material is light and durable, suitable for sports and outdoor activities, while providing high comfort. Titanium alloy material is durable and lightweight, with a textured appearance, suitable for daily wear. Stainless steel material is strong and durable, but heavier, suitable for infrequent wear.

Lens coating | More important

Recommended choice: Anti-reflective coating > Anti-scratch coating > Waterproof coating > Anti-oil coating

Popular science explanation: Anti-reflective coating can reduce reflections on the surface of the lens and improve visual clarity, especially in strong light. Anti-scratch coating can improve the durability of the lens, reduce scratches, and extend the service life. Waterproof coating can prevent water droplets from adhering, keep the lens clean, and improve wearing comfort. Anti-oil coating can prevent fingerprints and oil from adhering, keeping the lens clear.

Anti-glare effect | Very important

Recommended choice: 100% anti-glare > High-efficiency anti-glare > Ordinary anti-glare

Popular science explanation: 100% anti-glare lenses can effectively reduce glare, improve visual comfort and safety, especially in environments with strong sunlight. High-efficiency anti-glare lenses can reduce most glare, but the effect is slightly less than 100%. Although ordinary anti-glare lenses can also reduce some glare, the effect is limited in strong sunlight.
