If you're more sensitive to light, maybe you could try sunglasses or glasses with tinted lenses, or it wouldn't hurt to ask who you happen to be with if they could possibly dim the lights and use a few plug-in lights or lamps vs. overhead lighting. Lava lamps can also be a nice alternative to obnoxiously bright overhead lights - they generate enough light, and they're fun to watch.
I hope this is helpful.
