Due to Alexandra’s full Bane encasement leaving absolutely no opening and sealing her airtight, her natural sight will no longer work, and is therefore no longer needed, as it will be fully simulated with the brain implant by Lumina.
Because of that, and wanting to remove any possible issues or unnecessary biological systems, Alexandra’s eyes and eyelids are surgically removed. Into her empty eye-sockets, two orbs are inserted, that have all kinds of visual sensors built in. From Infrared, Ultrasonic, Lidar, Radar, and even a Geiger Counter, as well as a sensor for magnetic fields. The orbs themselves look like black spheres from the outside, before Alexandra’s face is encased.
To keep up the simulation from the brain implant, Lumina simulates her own existence into these sensors as well. As an example, Alexandra’s new Lidar view would still include her, even if she wasn’t actually there, due to being a projection by the neural implant.
The Helmet that, with the other sprayed on encasement layers, will be covering Alexandra’s head and embedded into the layers, is specifically made to allow for all these sensors to pass through it, without causing major disturbance. With this, and through the brain implant, Alexandra can see in far more ways than just optical, once she has finished her transformation. But her new senses are fully dependent and under absolute control of Lumina to properly pass and translate them for her brain.
