HOYA Free-Form and iDs technologies will take your patient’s vision to a completely new level.

Integrated Double Surface (iDS) design technology optimizes the surface geometry of progressive lenses by separating the design into two components on both sides of the lens.

• Patented, award-winning technology
• The vertical component which affects magnification changes from distance to near is placed on the front
• The horizontal component which affects magnification and power changes from side to side is placed on the back
• Virtually eliminates the "swimming" and "swaying" effects
• Perfect transition between far and near
