Hi Tim: Isn't that weird ! Yes, If my eyeball is looking down, & I try to close my eyelid, I can't, but if I look up, I can... Wait a minute - I don't know if the eyelid is closing more or, if because my pupil is raised higher, the little bit I CAN close the lid seems like more because the pupil is higher & therefor covered over !!!!!
Okay, next question: sounds like saran wrap & cling film is the same - it's clear, thin & 'hugs' a bowl when you wrap it around it ! - to make the 'greenhouse' effect you cut a piece of cling film to fit around your eye, enough so you can then tape the entire film all around the skin (I did it so the tape was above the eyebrow, on the bridge of the nose..) so no air can get in - then, you'll see in the morning 'dew drops' on the film !! It works great but sooo time consuming.
Good for you taking such care with your eye, I'm also a 'lubricant addict'.
Best wishes Tim, Nancy
