I am partially sighted, I have a referral to a low vision clinic. Since starting my new job with a lot more computing than I am used to my eyes have got sorer and dryer and headaches started to develop earlier and earlier in the day. It has got to the point where I now have severe headeaches most of the day or even when I wake up and find myself very light sensitive towards the evening and getting slight blurring at the edge of my vision. We have tried altering font size, increasing light levels and I am not constantly looking at screen with regular short breaks. I have been to an optician who could not find a prescription that would make much difference. I was taking paraceamol at times but didn't want to take it over prolonged periods. Any suggestions?
