I've never had that issue, the prescription is always an immediate improvement.
There could be reasons like the glass being much bigger or smaller than before, same for the prescription. Also the thickness of the glass. If you go from thick to the ultimate possible reduction...or viceversa, it could take a few days. Last time it happened to me was cause I went with big glasses and it took a while to get adjusted to them. But you should be seeing sharper anyway.
The lens are bigger on my last pair. I figured that's why the peripheral is slightly distorted on the new pair. I do see sharper when I look directly at objects from front view, but the peripheral vision from the lens is blurry.That's normal, it'll take a while to adapt.

Can you see out of the new pair of glasses?
My last 3 pairs of glasses I have gotten in the states have all came back wrong the first time, and not only could I not see out of them, but they caused headaches/migraines.
I can see fine when I look straightforward. When I look out the sides of the lens, it's distorted and blurry. And yes, I do have a bit of a headache.
