We provide a variety of lens types to suit different needs, including standard single vision, progressive, reading, and non-prescription lenses.

Within each prescription category, you can choose from a range of functional upgrades:

• Standard clear lenses: High-quality, everyday clear lenses.
• Blue-violet light filtering lenses: Reduce exposure to blue-violet light from screens and sunlight.
• Anti-reflective lenses: Minimize glare and eye strain, ideal for screen use, reading, and night driving.
• Fog-free + blue light lenses: Stay fog-free while protecting your eyes from blue light—great for any activity.
• High-performance gaming lenses: Enhanced clarity and protection from intense blue and UV light.
• Photochromic & blue-violet light filtering lenses: 2-in-1 lenses that automatically darken outdoors for maximum convenience.

For the same prescription, we offer multiple lens thickness options. The final edge thickness depends on your frame shape and your PD. Generally, a higher lens index (such as 1.67 or 1.74) results in thinner and lighter lenses. Here’s a quick guide:

Basic Index 1.56

• Up to 15% thinner and lighter than conventional plastic lenses.
• Best for prescriptions up to ±2.00 diopters.
• Recommended for mild prescriptions.

Standard Index 1.61

• Up to 25% thinner and lighter than conventional lenses.
• Best for prescriptions up to ±4.00 diopters.
• Recommended for mild to moderate prescriptions.

Premium Index 1.67

• Up to 40% thinner and lighter than conventional lenses.
• Ideal for prescriptions from ±4.00 to ±6.00 diopters.
• Recommended for moderate to high prescriptions.

Excellence Index 1.74

• Up to 60% thinner and lighter than conventional lenses.
• Best for prescriptions above ±6.00 diopters.
• Recommended for high prescriptions.

We offer a range of thickness options so you can choose the best fit for your needs. If you have further questions, our team is always happy to help!
