Facial Wrap is a single curved front that follows the line of the face and continues past the outer corner of the eye, so there is no open gap at the temple where a conventional frame ends. That matters for anyone whose trouble is not only what they look at but what arrives from the side, from a window, a passing car, a ceiling strip. There is no published frame geometry for this piece because it does not size the way a rimmed frame does.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sxd-sec\"\u003e\n\u003cdiv class=\"sxd-k\"\u003eTwo tints, two jobs\u003c\/div\u003e\n\u003ch2\u003eWrap coverage in two tint depths\u003c\/h2\u003e\n\u003cdiv class=\"sxd-grid\"\u003e\n\u003cdiv class=\"sxd-card\"\u003e\n\u003cb\u003eFL-41 Light\u003c\/b\u003e\u003cem\u003eLong indoor stretches\u003c\/em\u003e\u003cspan\u003eLighter rose, same engineering.
