3. Lens Index: Thinner & Lighter Lenses
The refractive index measures how much light bends as it passes through the lens. A higher index means a thinner, lighter lens—especially important for stronger prescriptions.
- Refractive Index
- Best For
- Thickness
- Price
- 1.60 index
- Mild to moderate prescriptions
- Up to 20% thinner than 1.5 index lenses
- $$
- 1.67 index
- Moderate to strong prescriptions
- Up to 30% thinner than 1.5 index lenses
- $$$
- 1.71 index
- Strong prescriptions
- Up to 35% thinner than 1.5 index lenses
- $$$$
- 1.74 index
- Very strong prescriptions
- Up to 40% thinner than 1.5 index lenses
- $$$$$
Which one should you pick?
- Low prescription (e.g., +/- 2.00 or less)? → 1.56 or 1.60 (saves money without excess thickness).
- Moderate prescription (e.g., +/- 3.00 to +/- 4.00)? → 1.67 (thinner and lighter).
- Strong prescription (e.g., +/- 5.00 to +/- 6.00)? → 1.71 (even sleeker).
- Very strong prescription (e.g., +/- 6.00+)? → 1.74 (thinnest and most comfortable).
