When lenses are off by even a few degrees, it can cause blurry vision. However, blurry vision can also occur as you adjust to a new pair of prescription lenses of the correct strength.
My doctor told me that it usually takes two to three days to adjust to a normal change in prescription, but the adjustment period last up to two weeks in some rare cases. After two to three days, check in with your eye doctor.
It's noemal, but if after one week of constant wear of your new glasses still don't feel right and you are experiencing headaches or blurred vision, talk to your eye doctor.
