For 3 years i been seeing line and patterns in my vision. I been to Eye Doctors many of time and they say my eyes was fine. Then every time i got outside my vision seem sensitive to light and then when i go inside my head starts to hurt and there's a pain feeling in the back of my eye then i'll go to sleep and my eyes feel puffy and dry, like the sensation of my eyes being swollen . I have anxiety disorder and stress that's about the only thing i have going on mentally with me. Can you go blind from this or is this blindness coming. I'm nearsighted and i have to wear glasses. Could this me allergies , migraine, stress ??? i dont know! :( if somebody help me figure this out would be relieved.
