A lot of the times i feel like the reason my eyelids droop is because of the dryness that can come about with smoking... It feels kinda like your eyelids stick to your eyes a little more. when you blink they kind of feel like it takes longer for them to return to the open position due to the friction? I just put some drops in not to rid my eyes of the redness, but to keep them well lubricated. Maybe? I hope so. My dad just laughs at me when my eyes scream i'm ripped out of my mind.
