Yes, I agree that's "rather poorly thought out ideas.".
In fact, I would say that is an understatement!
There is just so much wrong with that link's statement, isn't there!
just 3 of the things wrong with it;
1, It assumes we will idiotically choose to live in a dark place in the solar system when we already have got a perfectly good and well-lit planet called planet Earth we can live on that is vastly more hospitable to human life. When people have a choice, only the completely stupid would choose to reject living in comparative paradise in favor of living in a dark inhospitable place without a very good reason.
2, if we move to a dark place, why would we keep the lights off?
Hasn't this person heard of "artificial lighting"?
We would 'adapt' not by having bigger eyes but by keeping the lights on
3, if we leave the Earth's atmosphere, we will presumably need to ware space suits when we are outside buildings/space vessels. Both the space suits and the buildings/space vessels would presumably be deigned to block UV from entering in and reaching our eyes. Thus no "darker pigmentation" necessary.
If Mars is ever terraformed to have an oxygen rich atmosphere, it would naturally form its own ozone layer thus no "darker pigmentation" may be necessary even there and then.
