I'm not sure what is wrong with my eyes but I always have tension in my forehead, temples and eyes and sinusitus problems but today I tryed on my brother's glasses, which are far off from my prescription, and after a minute all the pain went away. What does this mean? He said they would give me headaches but they did the opposite. I think I'm sensitive to light. He is very near sited I believe. I could barely make out anything with his glasses. I don't have money right now to see a doctor about it, any suggestions?
