1.56 Blue Block Green Coating Single-Vision Finished Lens

● Balanced Optical Performance with 1.56 Index​
The 1.56 refractive index strikes an ideal balance between thinness and optical clarity. With an abbe value of approximately 39.5, it minimizes chromatic aberration (color distortion at lens edges), outperforming higher-index lenses that often sacrifice visual quality for slimness. Typically designed with an aspheric surface, these lenses further reduce spherical aberration, ensuring sharp, distortion-free vision for near, intermediate, and distance viewing.

● Enhanced Digital Eye Comfort (Blue Block)
Reduces Eye Strain: Filters a portion of High-Energy Visible (HEV) blue light emitted from digital screens (computers, phones, tablets), helping to alleviate symptoms of digital eye strain like headaches, dry eyes, and blurred vision.

● Crafted from high-quality resin, the lenses resist impact while the green coating adds a protective layer against daily wear. When combined with a standard hard coat, they achieve a scratch resistance, shielding against minor abrasions from dust or handling.
