well I can understand wanting to tape eyes open - I hope it goes w/o saying that you'd need a fine mist saline to wet their eyes - right?
A small steril kind I have used for eye injuries is called:
"Nature's Tears" an all natural, soothing eye mist.
call 1.800.for.mist or go to www.naturestears.com
I just know if my eyes are dry, it's not a comfortable situation...
Hope I've helped some PALS with this suggestion
