@nyrath You would think that this could be a solved problem, since it's not entirely dissimilar to the problem that car drivers face regularly because we make roads that point directly into the Sun.
To me, there is an obvious practical solution because of a lack of roads that force you to drive straight into the Sun.
You simply walk facing sideways to the Sun. You can shade your eyes from the Sun with the side of your helmet, and light reflected off your suit will provide adequate lighting.
