Want to shape this spiderman lens around the Faceshell so it fits perfectly against the shell Was wondering if someone can help me. I want ti be able to bend this lens around the spiderman faceshell so that it sits flush with the shell. I have tried shrinkwrap and adding depth after but it looks horrible. Any ideas please?

Thanks
You could scale the lens shape up on the y(?) axis to make it like a tube, move it so that it crosses the faceshell where you want it, then put a boolean modifier (subtract) on it so that it has one side flush fit. Next, delete all the other faces, then extrude what you have left to the desired thickness.
