Panoramic Asymmetric-Aspheric Design

High-curve spectacles are in ever greater demand, featuring outstanding fashionability and comfort of fit.
The significant tilting of the optical axis of this lens in respect of the line of vision produces "prism error," "mean power error" and "astigmatism" and causes eyestrain, sensations of swaying and blurring, under/over-correction and discomfort in binocular vision.

Problems with high-curve lenses up to the present
  • Problem1 Discomfort in binocular vision, blurring, under/over-currection

    Caused by mean power error and astigmatism occurring across the entire lens

  • Problem2 Eyestrain, blurring, under/over correction

    Caused by mean power error and astigmatism occurring at the lens centre

  • Problem3 Eyestrain, discomfort in binocular vision

    Caused by prism error occurring at the lens centre
