Standard/ 運動鏡架

PRF. Standard運動鏡架採環繞式設計，男女皆宜。
適合精緻臉型以及較窄的頭型。
PRF. Standard運動鏡架，適用於標準型的光學鏡夾(OPT. Clip)，需使用護鏡固定光學鏡夾，功能與PRF. PRO運動鏡架不相上下。

Support frame with a Wrap Around Design, unisex.
For extremely delicate faces and narrow heads. PFR. Frames can only be combined with the smaller OPT. Clip, which is inserted between the frame and the glasses without snapping into place. Apart from that. it is in no way inferior to the PFR. Frame PRO.
