I don't wear glasses at all bu t I need to slide the diopter all the way to the right to get sharp lines. Is this normal?
And I have suspected that when I use AF, I get nice and sharp images but sometimes when I MF I get not so sharp images.
Maybe my eyes are screwy and I need glasses?

My perscription for glasses is about -3.5 diopters, vision wise I think that leaves me at 20-70 vision or something like that. (i.e. I can see at 20 feet what most people can see at 70).
If I adjust the view finder all the way to the right, without glasses, I can see a good sharp image.
Now I can sort of see well enough to drive without glasses, but it is difficult when you are always looking over your shoulder to see what the sign you just passed said!
I think you should get your vision checked.
