For the same prescription, we offer different lens thickness options. The final thickness of the lens edge depends on the frame shape and pupil distance. If other conditions are the same, choosing a higher refractive index lens (e.g., 1.67 or 1.74) will make the lens thinner and lighter.
We offer a range of refractive index options for you to choose from, allowing you to select the best one for your needs:
- Comfort Lenses (Index 1.61): 20% thinner and lighter than standard lenses, recommended for prescriptions up to ±400 degrees.
- Premium Lenses (Index 1.67): 40% thinner and lighter than standard lenses, recommended for prescriptions up to ±600 degrees.
- Ultra-Thin Lenses (Index 1.74): 60% thinner and lighter than standard lenses, recommended for prescriptions above ±500 degrees.
