The CL1's rectangular frame provides more open airflow around the eyes, a less enclosed feel, and the traditional professional appearance preferred in some workplace cultures (lab, inspection, supervisory roles). If your primary hazard is particles coming from the front (drilling, grinding from ahead of you), the rectangular frame is adequate. If particles or splash from the side are a significant risk, a wraparound frame provides better coverage for that hazard.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border-bottom:1px solid #2a2a2a;margin-bottom:2px\"\u003e\u003csummary style=\"cursor:pointer;padding:12px 0;color:#e0e0e0;font-weight:600;list-style:none\"\u003eDoes the CL1 come with Amber — and is that the same as the BK1 Amber?\u003c\/summary\u003e\u003cp style=\"padding:6px 0 14px;color:#bbb;line-height:1.7;margin:0\"\u003eYes — the CL1 Amber (CL114\/Duramass) and BK1 Amber (BK114\/Duramass) provide the same contrast-enhancing tint in different frame styles.
