Lens index guide
Lens Index measures how efficiently light bends through the prescription lens. The higher a lens' index is, the thinner it becomes.
Quick Reference Chart
| Index | SPH Range | Thickness | Weight | Price |
| 1.56 | 0~±2.00 | Thickest | Heaviest | $ |
| 1.61 | 0~±4.00 | Moderate | Moderate | $$ |
| 1.67 | ±2.00~±6.00 | Thin | Light | $$$ |
| 1.74 | ±4.00+ | Thinnest | Lightest | $$$$ |
1.56 Index (Standard)
- Best for: Low prescriptions | SPH Range: 0~±2.00.
- Pros: Affordable, widely available.
- Cons: Thicker edges for stronger prescriptions; not recommended for sports sunglasses. It's the heaviest, not recommended for those who require comfort.
1.61 Index (Mid-Range)
- Best for: Mild to moderate prescriptions | SPH Range: 0~±4.00.
- Pros: Around 20-30% thinner than 1.56, good clarity. It's slightly lighter.
- Cons: Slightly more expensive.
1.67 Index (Thin & Light)
- Best for: Moderate to high prescriptions | SPH Range: ±2.00~±6.00.
- Pros: Around 40% thinner than 1.56, lightweight.
- Cons: Higher cost.
1.74 Index (Thinner)
- Best for: High prescriptions | SPH Range: ±4.00 and above.
- Pros: Thinnest option (around 50% thinner than 1.56). In terms of weight, it is the lightest and most comfortable.
- Cons: Most expensive.
Additional Tips
- Frame Size Matters: Larger frames make lenses appear thicker - opt for higher index(1.67/1.74) if needed.
- Ask Your Optician: For astigmatism (CYL) or bifocals, they may recommend adjustments.
