My head and eyes hurt while watching tv?

OK I'm a gammer and I play Minecraft alot.
My head started to hurt but I pushed through it.
The pain from my head went to my eyes and I started to cough. Can anyone tell me why this is happening. Today I meant to go to the hospital but a pipe broke and we couldn't drive through the water. I haven't been there for at least a year and I do not wear glasses
