That process is the reason a Heritage rim feels warm and slightly yielding against the skin rather than hard-edged, and it is the main thing separating this group from the rest of the range. Both sleep tints are offered on it, in zero power or with a prescription, and both carry the same measured transmission you will find on every lens we publish.\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\u003eAmber for the hours before, red for the hour after\u003c\/h2\u003e\n\u003cdiv class=\"sxd-grid\"\u003e\n\u003cdiv class=\"sxd-card\"\u003e\n\u003cb\u003eAmber lens\u003c\/b\u003e\u003cem\u003eEvening, indoors and outdoors\u003c\/em\u003e\u003cspan\u003e0.10% at 450 nm is the headline figure.
