A polarization filter is kinda likely maybe..
Show me one space-suit that doesn't have a polarysation filter
That can be built into the helmet and a simple lithium battery could power it for years. I have seen them on welding helmets and they seem fairly reliable, but I am unsure if that is really the case, I will have to ask my friend in the welding industry what their failure rates are.
No. The polarysation filter is a filter...it's a plastic membrane that an astronauts lovers when it's to bright. It polaryzes the light in one direction. It doesn't use power at all. The welding helmets uses liquid-crystal auto-darkening system, which uses power to change crystal configuration to let less sunlight get by. They are BTW, reely reliable.

Made with high tech manufacturing process but remaining simple to maintain, keep clean and service. Nothing there that does not have to be.
I disagree. You can use simplified computers, engines, electronics and everything else...but the suit MUST be the state-of-art equipement that help you deal with unseen problems. Tell me, what would you like to simplify? Life Support? Battery suply? Personal computer for communication? Lights? If something other like an IR camera will be used, and will breake how will it put the life of an astronaut in danger? On the other hand - how would the astronaut be endangered without an IR camera?
The thing I am trying to say is that space-suit is already super-advanced as it is, and adding non-essential equipement will not lower your chances of survival but make them higher.
Will adding an emergency SOS transponder to your suit will lower your chances of survival becouse you need more resources to maintain that suit?
Will adding GPS to let you know where you are will lover your chances of survival?
Will adding external suit-to-suit power/oxygen port will lower your chances of survival?
Will adding hud with a compas and a map on your helmet will lower your chances of survival during dust storm, which accurs 50% time on mars?
And if the suit is dammaged will the base-crew be able to rapair the suit at all?
I think I made my point.
BTW: the mars suit is currently beying tested. I will post how it looks very soon. There is no need to discuss here over something that hase been already exists.
