Dry Eyes

I went back to my opthamologist today because my eyes were burning and bloodshot. He said it isn't a result of the cataract surgery or inflammation, but is dry eye and use some drops for three weeks and then come back. It was a relief to know I don't have an infection. I told him I couldn't see how I could have dry eyes when my eyes were watering profusely. He said good tears have a little oil. Degraded tears are just salty and the eyes feel like something is in them, gritty, and burning. Well, that describes how they felt so I guess he's right.
