hi @sue225 When you say had no luck with hylo, was it because it didnt last very long giving relief? i find it doesnt coat my eyeballs like some others drops,but then again systane ultra makes my eyes feel sticky ;; i have learned one small thing after all these years, i was splashing the drops into eyes but not then carefully closing and wiping dropsoff eye lashes and i think the drops were sticking on my eyelashes/// not that i have many eyelashes left... but i am always nervous of introducint bacteria or germs when washing/wiping my eyes so i boiled and cooled some water and put 1/4 tsp salt in and dipped in one of those little round makeup pads and wiped my eyes... but didn't experiment long enough before tooth out and had a different cup water/salt to rinse my mouth; its like a mini hospital in my bedroom! I am going to give Refresh Celluvsic another try then......J. ps. it seems each new drop works for a bit then the eyes say; UH UH, nope, not doing it!!!
