"Although all of the aforementioned functional assessments of vision would be highly useful for astronauts, significant time and space limitations exist on the ISS. The addition of four additional tests of visual function may be a barrier given the current technology onboard the ISS. To address this issue, a head-mounted, multi-modal visual assessment system is currently being built to help detect the subtle visual impacts of SANS., This project is supported by NASA with the goal of developing a non-invasive framework for astronaut vision.
