So pages on the net say this is rare, but people have talked about it a lot, n my mom n I both have problems with some flashing lights, and I have light sensitivity in general. Depending on what condition my body is in at the moment. I havea lot of health issues, some lights seem to completely envelop me, some blinking lights will blink strongly inside of my head. Not really feeling like writing all this complicated stuff at the moment but am wondering what people with epilepsy also have problems with light sensitivity? N do you think some lights do it bc of toxic materials in them?
