Photosensitive epilepsy is a form of epilepsy in which seizures are triggered by visual stimuli that form patterns in time or space, such as flashing lights, bold, regular patterns, or regular moving patterns.

Visual stimuli in our houses comes from television, computer, electronic game sets, handphones, etc. According to an expert in UK, television is a highly seizure inducing electronic gadget because it has a refreshment rate of 50Hz (flashes) per second.

There are no strict and special guidelines to regulate light flashes on television and other visual stimuli gadgets. Just how often and long hours are we exposed to visual stimuli in a day? To be living in the 21st century and to totally avoid visual stimuli gadgets is an impossible thing to achieve. To overuse it is courting trouble. So, how can we adjust and regard our length of exposure to visual stimuli gadgets as reasonable and acceptable?

The responsibility is on each and every one of us to do it at our own moderate rate. Not too little and not too much.
