These are some questions about your past medical history and your current complaints that will allow me to provide you with the best explanation for your symptoms.
Which questions are you having difficulty understanding?
From your answers, I see that you have been dealing with this problem for 9 days now. There are a couple of possibilities to account for your symptoms.
1. Cataracts - These can cause blurry vision that is worse when the eyes are isolated. This blurryness is most prominent at night and when reading in dim conditions.
2. A microvascular accident - In this case, the eyes will become slightly crossed although it will usually not be evident to someone looking at your eyes. The vision can be interpreted as blurry or double. The symptoms resolve when either eye is covered but will be present when the eyes are being used together.
I recommend that you have a complete eye exam to evaluate for the above possibilities. In the event of cataracts, the solution is surgical removal. This is the most common surgery done in the United States and the results are usually excellent. If the diagnosis is a microvascular accident, the symptoms will resolve completely in 3 to 4 months.
I hope this is helpful and that you feel better soon...
