Eye Problem

In the morning, I have a hard time opening my left eye, and when it is open, it is so red. Is this problem caused by a problem in the nerves that connect to the eye or is it an eye or brain disorder? Because it feels like something from the inside stopping me from being able to open it. Also, even when it is open, it feels like there is a layer in it. I sleep well (7 - 9) hours a day. I dont have this problem with my right eye. Could somebody please tell me the cause or what is this case?
Thank You
