I am curious if any of you have had this problem or are aware of what could be the cause. About three or four weeks ago I started blinking excessively and uncontrollably. I blink so much that water builds up in the outside corners of my eyes which gets red and irritated because I am wiping the tears away so often. It is getting annoying and starting to hurt to blink so much. My eyes feel strained now. I wake up in the mornings with my eyes matted shut. They get matted throughout the day as I continue to blink. What could be the cause? It just started. Last week I was sick with the flu and slept quite a bit for about three days. During that time I did not blink as much, maybe because I wasn't using them. I have scheduled an appointment with an eye doctor, but it is a week away. Anyone have any ideas? I am hoping it is something that the eye doctor can fix. Could it be mental?
