Lately, mostly at night, I have been seeing what looks like a crecsent moon on the left side of my left eye. It seems to happen mostly at night and after I blink a few times. It also happens if I look downward with my left eye and then when I look up normally again, it is there. As I said, it mostly happens at night before bedtime. Could this be a sign of cataracts? I plan on making an appointment for an eye exam, but when this notice came up, I thought I would ask. Thank you for taking the time to read my email. Lucille Also, I do have floaters more in my left ey than the right. Again, thank you.
