# How will the future Mars Space Suit Helmet design protect Astronauts from Martian Radiation?

Mars Space Suit Helmet Visor's were mostly made up of polycarbonate [1], the same material used for EMU's visor for performing EVA in earth orbit. Meanwhile, Mars' radiation is 2.5x higher. How are we planning to tackle those issues? What new material might be used?

There is of course some UV from the Sun which can produce a nasty sunburn and cataracts in the eyes, but of course since sunlight drops as $$1/r^2$$ it will be significantly lower at Mars than at 1 AU. The face shield material(s) will be chosen to be absorbing of harmful UV light.
