Abstract
For reasons of comfort and appearance, eyeglasses that are increasingly lightweight, flat and thin are more and more in demand. However, the techniques able to reach significant results for the wearer, while maintaining maximum visual quality (acuity and distortion), are relatively limited. Basically, we can increase the index of the material [1], and flatten the base curve of the lens. In any case, it is necessary to maintain visual acuity in most of the gaze direction. It is the aim of aspherization [2]. But distortion and thickness reduction are only natural consequences of this compensation.
