So far my distance vision hasn't really been affected by the cataracts. It's working on the computer when I notice it. As I learned on Monday, I have two types of cataracts--the overall cloudiness that most people get, and also at least one dense spot. I don't know the terminology, but the problem occurs when light bounces off the clouded areas. Turning down the light on your computer screen can help. When you reach that point it's time to see an ophthalmologist.
