Vision went from 20/20 to 20/300 overnight?

I am a 34-year old woman with perfect eye sight that was reduced to below legal blindness in one night. My eyes have been extremely blurry for 4 days. The only thing I see as a possible cause is an LCD accident I had earlier this weekwhere I got the full brightness of a bulb inches from my eye. I was really concerned - it is the only accident I've ever had where I was worried I hurt my vision. I got spots in my eyes and then a couple days later my vision got cloudy. By the following morning my vision fell to 20/300. I've seen two Opthalmologists (one a retina/macula specialists) who can't see anything wrong. I am having an MRI for a dorsal hemmorage tomorrow. I'm so worried. What could do this??? What should I do?
