Description:

During the trial-wearing process of prescription glasses, it takes about a week to adapt. Some discomforts that begin to appear are normal, such as dizziness, eye swelling, distortion, etc. These symptoms usually disappear within two days. Anyone who wears glasses knows it. If you still cannot adapt within a week. Please contact our customer service. But it must be worn so that the eyes can adapt to the new frame.
