dry eye disease
"As I have gotten older my eyes have become quite irritated due to dry eyes. Usually they get very itchy and they burn a lot, and I have to scratch them a lot, which is not good for the eyes. I went to the optometrist and he prescribed me Systane which is OTC eye drops. I used them for about a year. They provide good temporary relief and were good for the short term, but they were never a permanent solution, and they made my eyes burn a lot, I saw mediocre result with them. I then went to the eye doctor and he prescribed me Xiidra. He gave me a coupon, so the first month would be free. I noticed immediate results. The side effects were bad taste in mouth and blurry vision, but rarely do my eyes burn with them. My eyes look better also."
