Eyeglass frames aren't one-size-fits-all — every frame design is engineered around a nose-bridge height and width, a temple-to-temple distance, and a temple arm length. Frames stocked by most local shops in Thailand are largely designed and sourced around the facial proportions typical of the region's biggest customer base. That's not a flaw, it's simply how the local retail supply chain is built. But it means a frame that sits perfectly on one face shape can sit noticeably wrong on another.
If a frame's nose bridge sits higher or narrower than the width and height of your own nose bridge, the pads or plastic bridge won't have enough surface contact to grip properly, so the whole weight of the frame slides down instead of resting evenly. If the temple-to-temple width is too narrow for your head, the arms squeeze inward at the temples, creating that pinching pressure point that turns into a headache by the afternoon. Neither issue is about the strength of the frame or how "well-made" it is — it's simply a mismatch between the frame's built-in proportions and yours.
A frame that slides or pinches isn't something you have to live with. In most cases it's fixable — either by adjusting the frame you already have, or by choosing a frame built with a taller bridge and wider temple spacing from the start. This page is general information, not a medical diagnosis. If a frame is causing skin irritation, numbness, or persistent pain, come in and let us take a look.
