dry eye disease
"I'm 56 with dry eyes since my 20s. Eyes always red like I've been crying. Been using moisture drops for 30 years. Had a reaction to the preservative in the drops, switched to preservative free Retain, only at Walgreens, $23 for 30 vials. Helpful, not a cure, used them 6 to 8 times/day. When waking, eyes were always painfully dry. Tried EVERYTHING.

Last month I started on Xiidra. Helps a little, when I wake I actually make a bit of tears. Eyes are still very red and irritated. Taste no problem, burns/itches a few minutes after applying, but goes away. Still use moisture drops but not as often. Retail $585/mon, but Xiidra coupon for 1st mon free and $10/mon for as long as I use them. Wouldn't use if had to pay full."
