Eikonic Lens Design Demonstration
This demonstration allows students to experiment with the factors that influence induced aniseikonia in anisometropic spectacle lens design: back vertex power, lens material, minumum thickness,and base curve. Lens parameters (base curve and center thickness) can be manipulated to reduce the amount of induced aniseikonia expected.
This example show the predicted aniseikonia (from standard lens design) and
expected aniseikonia (from eikonic lens design) of a spectacle lens prescription with the following parameters:
- OD: +3.50DS / OS: +2.25DS
- Lens Material: CR 39
