Stephen wolfram turned me on to these goofy glasses (https://www.smithsonianmag.com/innovation/could-these-glasses-cure-your-motion-sickness-180969722/); https://www.smithsonianmag.com/innovation/could-these-glasse... his description said that he could code in the back of a car with them on. I find them very effective at reducing seasickness below decks. I won’t say there are no funny feelings being below with roll, but I will say I could definitely work hanging upside down angled to roll direction with only mild discomfort: a HUGE improvement over folk remedies. The way they Are said to work is the liquid in the glasses shows a real horizon and this settles your brain into being able to believe your inner ear. I think a less goofy version of this could be built out digitally on the inside of sunglasses; I think it would be pretty popular.
