Blurry Vision

I was just wondering , I have worn corrective lenses for all my life, and have had no real probles with my eyes.
In the last three weeks my vision has gone from reading street signs three to four blocks away to not being able to read them from 10 feet away. What could cause such a dramatic change in my sight, and what should I do about it?

You need an eye exam.
