Did you know that there are blood vessels in the eyes, which can detect the brain functions? We all know that unhealthy habits such as smoking, poor diet, alcohol consumption, lack of exercise, etc. are the main reasons for heart attack and stroke. This means that, if you notice that your eye veins are larger than usual, you should see your doctor immediately.
