This is my area of research. Vagus nerve stimulation can alter vestibular function and generate these symptoms. Vision and optic nerve stimulation directly influences this process.
It’s the reason people get car sick if they ride in the back seat but not in the front seat. It’s the reason people get sea sick, the cure is to focus on the horizon.
Half of the vagus nerve, which is the tenth cranial nerve, splits off in the brainstem and goes to the cerebellum. This area of the brain is responsible for balance and when police give a field sobriety test, they are testing the influence of alcohol on the cerebellum.
The vagus nerve is what gives us that gut feeling or knot in the stomach that often saves us from entering difficult experiences.

Heh, yeah quite a few of us have been there...
At any rate, I think not just these, but actual blinding weapons are of concern. Sure, they are banned by treaty - but some will ignore the treaty, and others will work the legal aspect. As long as the purpose isn’t “primarily” blinding, lasers are permitted on the battlefield, and are already in wide use including on crewed vehicles. Also systems can be pitched as “only temporarily dazzling the vision”...
The allure of blinding weapons is that a) they’re easily produced and deployed today b) they’re cheap and c) they would be very effective if employed, at least during the day. Many dangerous laser types don’t have a visible beam, but can still blind.
Read some of the worse accounts of cockpit laser illumination if you want to get a sense of how such weapons would affect people.
