Adaptive liquid crystal glasses for epilepsy sufferers.

[BJ]

I had a random thought when reading how a certain type of internet lowlife has been sending seizure inducing videos to known sufferers.

I'm sure you're familiar with the original Hitchhiker's Guide to the Galaxy series, and the novelty device in it called the Joo Janta Peril Sensitive Sunglasses, which work on the principle of the Ravenous Bugblatter Beast of Traal, which is

a wild animal from the planet of Traal, known for its never-ending hunger and its mind-boggling stupidity. The Guide calls the bugblatter the stupidest creature in the entire universe - so profoundly unintelligent that, if you can't see it, it assumes it can't see you.

In the presence of danger, the sunglasses of course immediately become opaque, rendering the wearer oblivious to all possible harm.

I'm thinking a liquid crystal lens, actuated by a small microcontroller could sense rapidly strobing light of the sort epilepsy sufferers are sensitive to and block it completely, or potentially flatten the light curve to something tolerable, perhaps even smooth it out altogether.

This started out a little tongue in cheek, but I'm thinking liquid crystal technology (you're looking at it right now I'm sure) has advanced to the point that driving glasses capable of completely nullifying street light and shadow strobing effects should be easily and cheaply feasible. One could even face down a Nullarbor trucker's "wall of light" with impunity.
