Advantages

 

Perfect balance between distance and near visual fields

IOT engineers have developed a new optimization model that generates better and more sophisticated progressive lenses. As a result, IOT has now even better control of the progression profile, and more fl exibility to distribute the unwanted astigmatism and create wider visual areas.

Alpha H45 is the update version of IOT Alpha H40 design. This design represents the most sophisticated designs with a great level of success. It maintains the same philosophy as the previous version but improves softness and usable areas. Developed to be eff ective at any distance, Alpha H45 is the perfect balance between far, intermediate a near vision. Its power distribution off ers not only clarity of vision at all distances, but also generous visual fi elds providing wearer and exceptional comfort to look at any gaze direction.

The increased benefits in the new version include:

  • Wider near visual field
  • More symmetric design, corridor is easier to be found
  • More stables areas for far and near vision
  • Lower level of unwanted astigmatism
  • Improvement of the general performance

Target & Positioning

  • Ideal for demanding customers
  • Premium all-Purpose Personalized Progressive Lens
