This comprehensive set includes all six interchangeable lens plates — #2, #3, #4, #5, #7, and #10 — plus an Optiloupe for additional magnification, all stored in a hard plastic case for protection and organization.\u003c\/p\u003e\u003cp\u003eDonegan's OptiVisor is \u003cstrong\u003eAmerica's #1 choice in head-mounted magnifiers and is made in the USA\u003c\/strong\u003e. Unlike competing head-mounted magnifiers that rely on plastic lenses, the OptiVisor uses \u003cstrong\u003especially ground and polished optical glass prismatic lenses\u003c\/strong\u003e — the only head-mounted magnifier to do so. This provides superior optical clarity and long-term durability. The lightweight design can be worn comfortably over eyeglasses, and lens plates swap out quickly to suit different tasks.\u003c\/p\u003e\u003cp\u003eWhen selecting a lens plate, consider your preferred \u003cstrong\u003eworking distance\u003c\/strong\u003e — the distance from the lens plate at which objects are in sharpest focus. A higher magnification brings you closer to your work, which may or may not suit your bench setup. The most popular lens among jewelers is the DA 5 (8-inch working distance), followed by the DA 3 (14 inches), DA 4 (10 inches), DA 10 (4 inches), and DA 2 (20 inches). For even greater magnification, attach the included Optiloupe over any lens plate.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIncludes all six OptiVisor lens plates: #2, #3, #4, #5, #7, and #10\u003c\/li\u003e\n\u003cli\u003eIncludes Optiloupe for additional close-up magnification\u003c\/li\u003e\n\u003cli\u003eStored in a protective hard plastic case\u003c\/li\u003e\n\u003cli\u003eOptical glass prismatic lenses — the only head-mounted magnifier using optical glass\u003c\/li\u003e\n\u003cli\u003eLenses are specially ground and polished for superior clarity and durability\u003c\/li\u003e\n\u003cli\u003eLens plates are easily interchangeable\u003c\/li\u003e\n\u003cli\u003eDesigned to be worn over eyeglasses\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eIncluded Lens Plates\u003c\/th\u003e\n\u003ctd\u003e#2, #3, #4, #5, #7, #10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens Material\u003c\/th\u003e\n\u003ctd\u003eOptical glass (prismatic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCase Type\u003c\/th\u003e\n\u003ctd\u003eHard plastic case\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eMade in the USA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eLens Plate Reference\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eLens Plate #\u003c\/th\u003e\n\u003cth\u003eMagnification\u003c\/th\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003ctd\u003e1‑1\/2×\u003c\/td\u003e\n\u003ctd\u003e20 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003ctd\u003e1‑3\/4×\u003c\/td\u003e\n\u003ctd\u003e14 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003ctd\u003e2×\u003c\/td\u003e\n\u003ctd\u003e10 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003ctd\u003e2‑1\/2×\u003c\/td\u003e\n\u003ctd\u003e8 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e7\u003c\/td\u003e\n\u003ctd\u003e2‑3\/4×\u003c\/td\u003e\n\u003ctd\u003e6 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e10\u003c\/td\u003e\n\u003ctd\u003e3‑1\/2×\u003c\/td\u003e\n\u003ctd\u003e4 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOptiVisor headband magnifier\u003c\/li\u003e\n\u003cli\u003eLens plates #2, #3, #4, #5, #7, and #10\u003c\/li\u003e\n\u003cli\u003eOptiloupe\u003c\/li\u003e\n\u003cli\u003eHard plastic storage case\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003eThe focal length listed for each lens plate represents the ideal working distance measured \u003cstrong\u003efrom the lens plate\u003c\/strong\u003e, not from the wearer's eyes.
