Performance of a holographic SVSL consisting of two HOEs embedded into a flat polymer sheet. The target prescription is − 4 dpt SPH and 0 dpt AST. SPH error (a), AST error (b) and CE (c) are plotted over the lens surface with 60 mm diameter. This purely holographic SVSLs exhibit larger AST error and larger CE of opposite sign than the refractive SVSLs introduced in Fig. 2. The performance of a hybrid SVSL consisting of two HOEs embedded into a spherical lens for the same target prescription is shown in parts d-f. Here, the contributions of the HOEs lead to slightly increased AST and strongly reduced CE compared to the refractive SVSLs introduced in Fig. 2. Parts g-i show the performance of a hybrid SVSL consisting of two HOEs embedded into an aspherical lens with an ASPH on the backside for the same prescription
