Trade-offs: Sin Green vs Norko Blue
- Color effect: Sin Green offers a subdued green that appears more natural on lighter eyes. Norko Blue provides a vivid blue that stands out even on darker eyes. Choose green for subtlety, blue for boldness.
- Fit and comfort: Sin Green (8.5mm base curve) fits tighter corneas. Norko Blue (8.6mm base curve) is slightly flatter, which may cause movement if your cornea is steeper. Check your eye's base curve with an optometrist before ordering.
- Prescription range: Both lenses offer plano (0.00) to -8.00 power, covering non-prescription wear and moderate myopia. If you need correction, select your exact power; plano is available for cosmetic use.
