We present here the development of a physical human eye model – based on hybrid soft/rigid materials - in order to create a test bench reproducing the optical eye properties. Current literature does not cover properly the optical parameters of soft materials constituting the human eye.
For that reason, we first investigate the reflection and transmission spectrums as well as the refractive index of the different parts of a porcine eye – which is close to human one. The extraction of the optical parameters (absorption and scattering coefficients, reflection and transmission percentages of every part of the eye), allow the fabrication of a physical device mimicking a real eye. We are using materials which can model as finely as possible every part of the eye, particularly for the sclera or the iris which is often neglected. We present a soft actuated model of the iris where the aperture ranges from 1 mm to 8 mm. Finally, all the different parts are put together to obtain a device mimicking exactly the optical properties of an eye.
