dry eye disease
"I had an eye test and found that my vision was much worse.  While waiting for my new lenses she gave me Xiidra eye drops and a coupon, plus some Systane eye drops that I used just over a month (33 days). After a month of Xiitra/Systane my vision changed drastically. She ran another eye exam and showed me the difference of both exams. My last exam was perfect compared to a month ago which was unrecognizable letters. The best insurance offered my wife as an RN won't cover Xiitra. That's $500+ a month to you and me."
