UV Protection | Outdoor activities, sunny environments | Industry: UV400 (Blocks 99% UVA/UVB) Base: UV400 + anti-reflective coating (▲) Advanced: UV400 + nano-coating (▲▲) | Shields eyes from harmful rays; Advanced tier reduces glare for clearer vision. | Higher cost for advanced coatings; basic tier lacks premium features. |
Transition Speed | Driving, variable light conditions | Industry: 30–60 sec (standard) Base: 20–30 sec (▲) Advanced: 10–15 sec (▲▲) | Quick adaptation to light changes; ideal for fast-paced environments. | Slower tiers may lag in rapidly changing light (e.g., entering a tunnel). |
Lens Material | Sports, active lifestyles | Industry: CR-39 plastic (standard) Base: PC (lightweight, impact-resistant ▲) Advanced: Trivex (ultra-light, 50% thinner ▲▲) | Enhanced durability and comfort; Advanced tiers reduce weight for long wear. | Trivex may cost more; CR-39 lacks impact resistance. |
Weight | All-day wear, reading glasses | Industry: 25g (standard) Base: 20g (▲) Advanced: 15g (▲▲) | Lightweight design reduces pressure on ears/nose; Advanced ideal for sensitive users. | Heavier tiers may cause discomfort during prolonged use. |
Blue Light Blocking | Office work, digital device use | Industry: 30% (basic) Base: 40% (TÜV-certified ▲) Advanced: 50% + anti-fatigue coating (▲▲) | Reduces eye strain from screens; Advanced tier minimizes digital fatigue. | Lower tiers may insufficient for prolonged screen use; coatings add cost. |
Frame Durability | Daily wear, rugged environments | Industry: Standard plastic (scratch-prone) Base: Reinforced PC (scratch-resistant ▲) Advanced: Carbon-fiber composite (▲▲) | Base resists minor scratches; Advanced withstands extreme conditions. | Standard frames may degrade faster; carbon-fiber adds bulk. |
