From few days nearly 8-10, I am not able to open my eyes continuously in light and in shiny areas. I have to see very forcefully due to which headache starts. Actually it is not headache but a pressure for staring my eyes in daylight. I have to see forcefully and wrinkle comes on my forehead, I get relief when I close my eyes for some time or come in a dark place. I also can't watch TV or operate mobile for more than 10-15 minutes, the same problem persists. Not every time but when I am in area which have proper light for large time then vomiting occurs. I have gone for eyesight test which is normal. Please give me idea that these symptoms are related to which disease? What I can do in these conditions? I am also taking following medicines for bipolar disorder :- 1- Lithium carbonate prolonged - release tablets I.p. 400 mg (1 tablet in morning & 1 in night) 2-Bupropion Hydrochloride extended release (1 tab in mor & 1 in nig) 3-Rabeprazole sodium 20 mg (1 tab in mor) 4-Lurasidone Hydrochloride 40 mg (1/2 tab at night)
