Thinner, more comfortable, thin, double-surface aspherical plastic lenses
Introducing ideal comfort made possible by our double-surface aspherical BI-AS design. These lenses thoroughly meet the needs of customers looking for a thinner, more comfortable, and more attractive choice.
We employed our new in-house concept of design by BI-AS-exclusive type and designed our Shapely brand lenses with an emphasis on making lens thinner. By harnessing our proprietary aberration (distortions and blurring) control tool, we were able to realize unsurpassed thinness and lightness. We designed our Clearly brand lenses with an emphasis on vision by prioritizing the amelioration of aberrations. A natural field of view through all corners of these lenses was realized with minimal distortions and blurring. In every case, we consider power, curves, lens thickness, and size after receiving an order and apply an ideal aspherical design to each individual lens. A clear, natural field of view through all corners of each lens is attained with limited distortions and blurring by carefully correcting the balance between power disparities in the peripheral portion of the lens and the astigmatism of the wearer and ensuring a sharp, clear view extending to the peripheral portion of the lens.
