Can't See

I finally went to the optometrist to have my eyes checked. I like the Dr. very much. However, now I can't see out of my left eye. First, the tech puffed air into my eye and performed some other test before I saw the Dr. Then, I did well while the Dr. checked my vision without my contacts or glasses. It was determined that my vision hadn't changed. That is a good thing. So, she had me try a new brand of contacts which I was more than willing to do. However, once I had those in and got back in the chair to see where my vision stood, it was realized that I couldn't see out of my left eye at all. Couldn't read one darn letter...in fact, the chart looked like a blur of white. She had me put in a contact that was even stronger and still the same outcome. And, now that I have taken the contact out, I still can't see very well. Things continue to be pretty blurry even with my glasses on. What on earth has happened to my left eye? I am hoping that a good night's sleep will solve the problem. Keep your fingers crossed. Maybe messing with an ok thing isn't such a good thing?! The right eye was great however. The contact was awesome in the right eye and felt great.
