Hello, The past couple of fall seasons I have been waking up random days with my right eye (and its always only my right) eye red, crusty and slightly sensitive to light. It does not itch and will sometimes later in the day start to go away, somedays it will stay all day. It always seems to happen at the same time of year as well and only when I sleep. I don't believe its pink eye as there is no discharge or oozing. It will always be just be dark red and tired looking, while my left eye is fine
