I have consult to my doc about my problem and he advise me to regular use of PG 400 eye drop. I am using this eye drop from last three years and it is giving relief to me but the relief is not permanent. Whenever i forget to use this eye drop then my headache again strongly hit me. I feel very week after one hr headache. My question is what kind of food/diet i should use? And what kind things i should not eat in my food? Is there any other way to keep my eye proper while not using the eyedrop PG400
