摘要: A variable geometry contact lens structure having a thickness t sufficient to carry an active payload is constructed using layers of materials with high oxygen transmissibility and low transmissibility. The layer provide mechanical support for the payload, adequate transmission cornea user's eye. ratio thicknesses two changes abruptly at boundaries between non-payload regions structure. For example, boundary region, t1 t2, R=t1/t2, by least 2:1 over lateral distance not more than t.
