This thesis introduces open.lens, an open-source project designed to democratize access to precision vision through the recovery and integration of optical components considered obsolete. The research stems from the analysis of an evolutionary mismatch: the discrepancy between the human visual apparatus, evolved for distance vision, and the pressing demands of modern manufacturing, which imposes prolonged proximal efforts with consequent risks of asthenopia and musculoskeletal disorders. Through a methodology combining extensive desk research with ethnographic analysis conducted in artisan workshops, including goldsmithing, wax modeling, and glassworking, the latent needs of artisans and the entry barriers of the current market were mapped. This market is characterized by a sharp polarization between inefficient low-cost devices and professional instrumentation with prohibitive costs. open.lens addresses these critical issues by proposing a hybrid digital magnification system. The project is based on the principle of technological upcycling, pairing high-resolution vintage analog photographic lenses with still-functional used webcam sensors, all supported by a modular architecture composed of aluminum profiles and 3D-printed joints. The results demonstrate how an open and distributed design approach not only reduces the ecological footprint associated with the production of new hardware but also offers a professional, repairable, and customizable solution, capable of transforming visual support from a simple corrective aid into a tool for enhancing precision performance.
Il presente lavoro di tesi introduce open.lens, un progetto open source progettato per democratizzare l'accesso alla visione di precisione attraverso il recupero e l'integrazione di componenti ottici considerati obsoleti. La ricerca muove dall'analisi di un disallineamento evolutivo: la discrepanza tra l'apparato visivo umano, evolutosi per la visione a distanza, e le pressanti richieste della moderna manifattura, che impone sforzi prossimali prolungati con conseguenti rischi di astenopia e patologie muscolo-scheletriche. Attraverso una metodologia che coniuga un'estesa desk research a un'analisi etnografica condotta presso laboratori artigiani, includendo l’oreficeria, la modellazione della cera e la lavorazione del vetro, sono stati mappati i bisogni latenti degli artigiani e le barriere d'ingresso del mercato attuale, caratterizzato da una netta polarizzazione tra dispositivi low-cost inefficienti e strumentazioni professionali dai costi proibitivi. open.lens risponde a queste criticità proponendo un sistema di ingrandimento digitale ibrido. Il progetto si basa sul principio dell'upcycling tecnologico, accoppiando obiettivi fotografici analogici vintage ad alta risoluzione con sensori di webcam usate ancora funzionanti, il tutto sostenuto da un'architettura modulare composta da profili di alluminio e da giunti in stampa 3D. Il risultato dimostra come l'approccio del design aperto e distribuito non solo abbatta l'impronta ecologica legata alla produzione di nuovo hardware, ma offra una soluzione professionale, riparabile e personalizzabile, capace di trasformare il supporto visivo da semplice ausilio correttivo a strumento di potenziamento della performance di precisione.

Abstract
This thesis introduces open.lens, an open-source project designed to democratize access to precision vision through the recovery and integration of optical components considered obsolete. The research stems from the analysis of an evolutionary mismatch: the discrepancy between the human visual apparatus, evolved for distance vision, and the pressing demands of modern manufacturing, which imposes prolonged proximal efforts with consequent risks of asthenopia and musculoskeletal disorders. Through a methodology combining extensive desk research with ethnographic analysis conducted in artisan workshops, including goldsmithing, wax modeling, and glassworking, the latent needs of artisans and the entry barriers of the current market were mapped. This market is characterized by a sharp polarization between inefficient low-cost devices and professional instrumentation with prohibitive costs. open.lens addresses these critical issues by proposing a hybrid digital magnification system. The project is based on the principle of technological upcycling, pairing high-resolution vintage analog photographic lenses with still-functional used webcam sensors, all supported by a modular architecture composed of aluminum profiles and 3D-printed joints. The results demonstrate how an open and distributed design approach not only reduces the ecological footprint associated with the production of new hardware but also offers a professional, repairable, and customizable solution, capable of transforming visual support from a simple corrective aid into a tool for enhancing precision performance.| File | Dimensione | Formato | |
