baffled

I went to the eye Dr. this morning for the third time this week. I am having trouble with my glasses. Last week I went because one of the lenses was cracking and I wanted a replacement before the warranty ran out. They recommended plastic lenses so I agreed and they ordered them. I went Tuesday night to have them installed. They didn't feel right, so the optician double checked everything and said all was good and wrote it off to the fact that I had my glasses off while they were changing them. Ok. All the rest of the evening I couldn't wear them. My eyes felt super tired whenever I had them on. Everything is clear, but distorted in a subtle way. Went back the next day they cut new lenses out of a different material, and it initially seemed better, but till I got home and wore them an hour, same problem. Went back today, same thing, we have the right prescription in them, there is nothing we can change. They tweaked the angle and it seemed better initially, but till later in the day, no go: flat surfaces all look like they are angling off to my left. It is really frustrating. They say everything is right and there is nothing more they can do. I am left with glasses that do not help me and I can not wear. What to do?!?? Fortunately I can do ok without glasses, but it feels like I will never get my glasses back and I am starting to miss them.

PS Really, I just needed to vent!
