I'm 22 years old, near sighted with astigmatism in each eye. I've worn my glasses since I was 7, my newest prescription is like -6.50 in left -7.50 in right I'm not sure exactly but that's close, I've been having issues since December and I've been driving myself and everyone around me nuts. Let's get started, for one I do not drink water AT ALL. I don't drink really at all through out the day I'm always dehydrated, I eat mainly salty foods so I'm working on a healthier diet. My symptoms are headaches they happen every day I have spontaneous bright spots that turn into dark purplish spots and go away, this happens without standing up. I'll sometimes get random bright spots that last a minute or two the fade, and then I'll get bright squiggly zig zag kind of lines in center vision a few times daily, also in my left eye in my top and bottom peripheral vision I have this shadow type thing it's hard to explain but I can see through it and I'm guessing that could be from either optic neve damage or surfers eye I have the yellow line next to my iris, it's developed over time but got worse when I got pregnant, my son will be a year old next month. Another thing my prescription is pretty old it's 5 years old so I'm pretty sure my eyes are straining, I can't afford new glasses at the moment so I'm trying to do the best I can with what I have. I have been to my eye doctor many times and in my opinion he's done a great job I got a comprehensive dialated eye exam and he also took photos of my retinas which everything was healthy he didn't find problems and gave me eye drops for dry eyes. I tend to obsess when I have a problem and I'm probably creating problems in my head but eyes are a serious thing!!!!
