{"product_id":"watchmakers-eye-loupe","title":"Watchmaker's eye loupe","description":"\u003cp\u003eA handheld loupe costs you a hand. This one wedges into the eye socket and stays there, and that is the whole reason watchmakers use this shape and not a nicer-looking one.\u003c\/p\u003e\n\u003cp\u003eBlack barrel with a threaded eyecup, supplied with the soft ring that grips the orbit.\u003c\/p\u003e\n\u003ch3\u003eHow you actually wear it\u003c\/h3\u003e\n\u003cp\u003eIt is held by the muscles around the eye, not by the brow. Raise the cheek and lower the brow slightly and the socket closes on the ring; relax and it drops out. Everyone drops it a few times on the first day and then never again.\u003c\/p\u003e\n\u003cp\u003eWear it on whichever eye you naturally close things with, and keep the other eye open. Closing the second eye for an hour is what gives people a headache, not the loupe.\u003c\/p\u003e\n\u003ch3\u003ePick the number honestly\u003c\/h3\u003e\n\u003cp\u003eMagnification and working distance trade against each other, always. The higher the number, the closer your face has to be and the smaller the patch you can see.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3X and 5X\u003c\/strong\u003e are for working - fitting a hand, seating a screw, cleaning a case. You have room for tweezers between the lens and the work.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e10X\u003c\/strong\u003e is the general inspection figure. It is what most people reach for and what most jewellery grading is quoted at.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e15X and 20X\u003c\/strong\u003e are for looking, not for doing. At 20X you are roughly a centimetre from the part and the field is smaller than a match head. It shows you whether a pivot is bent; it will not let you work on it.\u003c\/p\u003e\n\u003ch3\u003eWhere it stops\u003c\/h3\u003e\n\u003cp\u003eThis is a single lens, not an achromatic triplet. That means colour fringing at the edge of the field and softening as you move off centre - visible at 10X and obvious at 20X. Our triplet loupe is the one to hold for colour-critical inspection; this is the one to wear for everything else.\u003c\/p\u003e\n\u003cp\u003eThe stated magnification on loupes in this class is the manufacturer's figure, not a measured one, and the convention across the whole category is generous. Read the numbers as a ladder that is ordered correctly rather than as calibrated optics.\u003c\/p\u003e\n\u003cp\u003eIt does not correct for your prescription. If you work in glasses, you will be taking them off.\u003c\/p\u003e","brand":"Mikrabench","offers":[{"title":"3X","offer_id":47513363284159,"sku":null,"price":14.99,"currency_code":"USD","in_stock":true},{"title":"5X","offer_id":47513363316927,"sku":null,"price":14.99,"currency_code":"USD","in_stock":true},{"title":"10X","offer_id":47513363349695,"sku":null,"price":14.99,"currency_code":"USD","in_stock":true},{"title":"15X","offer_id":47513363382463,"sku":null,"price":14.99,"currency_code":"USD","in_stock":true},{"title":"20X","offer_id":47513363415231,"sku":null,"price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/5826\/3743\/files\/S2f17723055de427788ebe683723fab16i.webp?v=1789885845","url":"https:\/\/arvonelle.com\/products\/watchmakers-eye-loupe","provider":"ARVONELLE","version":"1.0","type":"link"}
