Sudden Blurry Vision
An abrupt and dramatic loss of vision may be a sign of a problem with the blood flow to your eye or your brain. Immediate medical attention can prevent serious damage and may even save your life. Even if your vision gets better quickly, it might still be a warning of a stroke or the beginning of a migraine headache
This can be a sign of diabetes, which causes too much sugar in your blood. If it isn’t well managed, you may get diabetic retinopathy (when tiny blood vessels in your eyes leak blood and other fluids). You may have blurred vision and find it hard to see at night. Doctors can use a laser to seal the leaks and get rid of unwanted new blood vessels. This may affect your side vision, but it can save your central vision.Look at the entire slideshow here.
