Lens Materials
Compare materials by index (thickness potential) & Abbe (clarity)
Tip: Higher index can reduce thickness, while higher Abbe improves clarity (less chromatic blur).
| Material | Index | Abbe (Clarity) | Best Use |
|---|---|---|---|
| CR-39 (Standard Plastic) Great optics • economical |
1.50 | 58 (Excellent) | Low-to-moderate Rx, best clarity |
| Trivex (Premium Safety) Lightweight • tough |
1.53 | 45 (Good) | Rimless, kids, safety & comfort |
| Mid-Index Balanced thickness/value |
1.56 | 36 (Moderate) | Everyday wear, moderate Rx |
| Polycarbonate (Impact Resistant) Strong • thinner than CR-39 |
1.59 | 30 (Lower) | Kids, safety, sports (AR recommended) |
| High Index (Everyday Thin) Better cosmetics for stronger Rx |
1.60 | 42 (Good) | Moderate-to-high Rx, thinner look |
| Super High Index Noticeably thinner for high Rx |
1.67 | 32 (Lower) | High Rx cosmetics (AR strongly advised) |
| Ultra High Index Maximum thinning for very high Rx |
1.74 | 33 (Lower) | Very high Rx when thickness is priority |
