I've been having blurred central vision off and on for two months now, what should i do and what is the possible cause?

Hard to say for sure: An appointment with an eye md will comprehensively evaluate your eyes and provide you with an answer. Blurry vision may have a myriad of possible causes, some as simple as needing a pair of glasses. Medical problems would have to be figured out during the exam. Good luck.

Get checked: Blurred central vision may indicate central serous a condition that is found in young healthy people. Other conditions such as epiretinal membranes, idiopathic neovascular membranes need to be ruled out. See your eyecare professional.
