this is model is titainum. P-titainum. means not 100% pure titainum. that's why the price so cheap. we often called this is half titainum glasses. because the frame is not titanium. only two temples are titainum. but have to do IP plate. this frame the weight will around 2 g more than pure titainum. but cost go down too much. The biggest advantage of titanium is that it is skin-friendly and non-allergenic. And only two temples in contact with the skin.

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.
