Contacts vs glasses.... But what is with contacts AND glasses hurting my eyes?

So here is the deal: I wore glasses about 4-5 years ago, and their main purpose was to help me be able to see things from a great distance. Like the lecture board 300 feet away in a large university classroom, or signs on the freeway posted some 1/2 a mile away. The problem with the glasses several years back was the strain it caused on my eyes: simply put they felt that they were too powerful. Light colors, whites and yellows in rooms would strain my eyes so bad. I had them change the prescription with 3 different eye exams and I still had the same problem. In 2007 I did away with the glasses, and my eye sight got slightly better. It was still a challenge driving in pitch black at night, but I still could see the signs and speed limits blurred from a far, but well defined within close proximity. So, a few days ago, I wanted to get contacts. I felt I needed to go ahead and get some so I can see blurry things much better. The eye doctor said I had a very slight form of astigmatism, very very small! So I left with contacts. They were brilliant! Problem was... Everything up close is blurry! Far away is vibrant and feels like a 3D movie! Lol! I was informed to wear my contacts for the first day for a few hours. About five hours the second day, six to eight the third, with a couple hours at night. It has been five days and the left eye contact seems fine. I called the eye doctor's office about the right being slightly blurry and not as strong. The mentioned, "well your vision in your right eye is stronger than your left that's why it seems like that." so that I am partially confused. If my right eye is stronger than my left eye, why would the contact be blurry when worn!!!??? And now here is the kicker. When driving on residential streets, without contacts and without lenses, the street signs are just fine! Yesterday after I took off my contacts and I took an hour nap, I drove around the neighborhood and my eye sights is blurrier than it ever was! What gives??
