|| Rule 1: do not cause your customer to vomit

Just been in two shops with malfunctioning halogen lighbulbs, flickering in that very special way that attempt to make me pass out and/or vomit.|
I'm wondering how widely shared this reaction is...
Are you sensitive to flashing / flickering lights?
Usually a headache rather than the symptoms you describe.
Oh now! Now I am no longer pure, pristine and white!
They tend to set off my migraines after a while, I'm not photosensitive luckily.
I also get a headache if the flickering/flashing goes on for too long. I am terrible with strobe light in clubs, me.... :(
I can get queasy too. The worst thing is the flicker caused by sunlight through leaves when driving. I get a bit car sick anyway but the flicker makes it worse.
If I'm feeling twitchy lights or noises can bring on a panic attack. Or a headache.
I tend to be only sensitive to it if I've got a bit of a headache already. Bright flashing lights that mean I can't see a wall mean I fall over (eg lots of nightclubs). I'm more sensitive to thumpy noises where I feel the vibration.
Oh god yes, nightclubs with heavy bass (for people on base ;) make me feel incredibly sick.
Strangely I'm fine in a club as the music causes all sorts of vibrations, but music at a level like in restaurants is bad as I hear it solely like hammering on the wall.
The upstairs room in Slimelight has too much moving lighting for me to stand, so I have to get someone to hold me up and help me walk with my eyes shut through it, each time I go to the loo. At least the bar staff didn't think I was on anything after I started walking just fine at the other end!
The bar staff at Slimelight are probably fairly confused by seeing a customer who isn't on anything.
Indeed, but after the initial surprise they were a lot less judgemental than in many places. If I were going to get off my face on pharmaceuticals, do they really think I'd be in Virgin Megastore, for example?
I danced in a very ill fated production of Alice in Wonderland years ago. Being low budget they created the 'falling down the rabbit hole' effect by having Alice on a 10 foot ladder being spun one way, with 2 wreaths of dancers spinning around the ladder in opposite directions. They added flashing lights and a strobe, and every performance without fail I finished my sequence, aimed blindly for the wings, ran head first into drapes and crashed into the wall. I've never got on with anythng that's flashed since then, unless it's a pretty goth love!
It's fairly rare for me, but when it happens usually I'll get eye pain and/or a headache, followed by nausea or dizzyness.
I actually quite like rapidly strobing lights, for the way they tend to chop motion up into lots of little discrete jumps.
I get horrible headaches/migraines from flickering lights sometimes, and a dull headache at other times. Same for monitors running at <70Hz. I collapsed a couple of times at secondary school because of the lights in our physics lab flickered noticably to me, I complained after the first time but they didn't believe me.
I suspect the headache/migraine is secondary to vertigo induced by the lights. I currently have severe vestibular dysfunction and I don't notice dizziness till I'm at the vomiting/severe headache stage. Last time I was badly affected it was from a friend's monitor, and I spent 3 days with migraine type things because I didn't consciously notice the symptoms till I was already badly affected.
As a result I am super cautious of flickering lights and monitors. I won't stay near them and will turn them off where possible. It is probably a reasonable health and safety request to tell the shops that people are affected by flicker and could they fix it or turn it off. I won't stay in a shop/place with flickering lights. If it is a shop I'll just leave that area/shop but if it is a workplace I will ask them to fix the flickering or turn it off entirely. I guess I should alert shop employees to flickering horribleness so they can fix it.
I also get headaches from excessive fluorescant lighting like in a supermarket. It's just TOO bright and I suspect I am sensitive to the flickering. I take my hearing aid out so the noise on top doesn't send me loopy, but it's still difficult not to space out completely.
I've noticed that the flashing orange lights used by on brakedown trucks and the like really sets my nerves on edge to the extent that I have to shut my eyes when I'm passing one.
Adding my own checkboxes:
Other visual triggers are:
- excessively bright colours together, e.g. hot pink with lime green and electric blue,
- excessively bright lights, even when steady, and
- anything that causes flickering or flashing across my whole field of vision for a while, so intermittent strobe lighting is OK, but staring at a monitor with a low refresh rate isn't, which is not fun when IT departments disable changing of monitor settings.
