Typically, prescription glasses are built with a pair of lenses oriented in a straight line with very little deviation from 180° angle (Figure 1(a)). However, protective or sport goggles (no dioptres) are often curved and overall more ergonomic.
Is it possible to design more ergonomic prescription glasses that would follow a curvature of an axial cross-section of a human skull (Figure 1(b))? If not, what are the physical limitations here?
