We have sunglasses now that are UV resistant. I think it's not that
big of a jump to have dome surfaces that are too. Solar flares and
cosmic rays, now that might be a problem, and might be a technical
hurdle that would have to be overcome.

I was talking about tourism, not permanent settlement. The staff of
these tourist resorts would have to deal with this either by spending
alot of their time in rotating hubs on the martian surface that could
provide a full 1-g gravity, or by periodically leaving their jobs to
live somewhere that does, so their body can recover.
