My Eyes Bother Me A Night When I Go To

My eyes bother me a night when i go to sleep. It feels like sand in my eyes. I have to be real careful opening my eyes because when i open my eyes or even move my eyes with my lids closed they will get scatched. I usually have to pick my eyelids up to open my eyes. I put Refesh eyedrops in my eyes to help but it doesn't last long. My eyes usually don't bother me during the day. It's mainly at night when I sleep. I'm pretty sure I have dry eye. Any suggestions on what i can do to help. I've tried the gel tears but seems like those bother me more the the regular drops. Do you think having a humidifier would help?
