Simulation of a central scotoma using contact lenses with an opaque centre

ConclusionIt is possible to induce a gaze‐contingent absolute scotoma and hence mimic central vision loss using centrally‐opaque CLs provided that the CL opacity is larger than the entrance pupil of the eye. This simulation tool will, therefore, be ineffective at low environmental light levels (as shown previously) if the entrance pupil of the eye is larger than the CL opacity.
