2. Advanced Aspheric Lens Design

Traditional spherical lenses create a "coke-bottle" effect and a distorting "fishbowl" view. By flattening the lens curvature, our aspheric high-index lenses eliminate the "bug-eye" magnification in plus lenses and the face-shrinking effect in minus lenses.

Your Benefit:

  • ✔ More natural eye appearance
  • ✔ Wider field of view
  • ✔ Less peripheral distortion

Our premium 1.67 and 1.74 high-index lenses are especially beneficial for strong prescriptions, offering maximum thinness and lightness.

3. Certified Safety & Durability

The thinner a high-index prescription lens becomes, the more fragile and prone to scratches it can be in ordinary glasses. We rigorously test every lens to ensure real-world performance:

  • FDA Drop-Ball Impact Test: Lenses must withstand a steel ball dropped from 50 inches without shattering.
  • Steel Wool Scratch Test: Our premium hard coating offers 6 to 8 times greater scratch resistance than standard lenses.

Your Benefit:

  • ✔ FDA-compliant impact resistance
  • ✔ Advanced hard coating
  • ✔ Enhanced scratch resistance
  • ✔ Long-lasting durability
