Adaptation is normal. Your brain has to learn where in the lens to look for each distance, and for most people that takes somewhere between two days and two weeks.

But there is a line between adjusting and a genuine fitting error, and it is worth knowing where it sits. Come back to us if the reading area feels too low or too high no matter how you tilt your head; if one eye is consistently clearer than the other at every distance; if the corridor feels so narrow you are swinging your head to read a line of text; or if you are getting headaches that build through the day rather than easing off.

Any of those four usually means the measurement, not the lens. We remeasure and reglaze at no charge.
