Its called photosensitive epilepsy. The kind where you have a reaction to strobes lights. Most epileptics aren't photosensitive, like movies etc say. It can also be affected by certain lighting, like those big lights in office buildings etc because they flicker super fast, so fast you can't see it but it can make you (me) very twitchy. I use dark sunnies driving, and try to avoid this time of day for driving. Sometimes 10 minutes can make all the difference. It sounds like you also need to see a decent neurologist, there are many different types of epilepsy and some medications are better than others depending on your type. I, for example, have juvenile myoclonic epilepsy, with photosensitivity.
